| 1 | Performance and mechanism of Cr(Ⅵ)removal by zero-valent iron loaded onto expanded graphite显示文摘Zero-valent iron(ZⅥ) was loaded on expanded graphite(EG) to produce a composite material(EG-ZⅥ) for efficient removal of hexavalent chromium(Cr(Ⅵ)). EG and EG-ZⅥ were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM),Fourier-transform infrared(FTIR) spectroscopy and Brunauer–Emmett–Teller(BET) analysis. EG-ZⅥ had a high specific surface area and contained sub-micron sized particles of zero-valent iron. Batch experiments were employed to evaluate the Cr(Ⅵ) removal performance. The results showed that the Cr(Ⅵ) removal rate was 98.80% for EG-ZⅥ,which was higher than that for both EG(10.00%) and ZⅥ(29.80%). Furthermore, the removal rate of Cr(Ⅵ) by EG-ZⅥ showed little dependence on solution p H within a p H range of 1–9.Even at pH 11, a Cr(Ⅵ) removal rate of 62.44% was obtained after reaction for 1 hr. EG-ZⅥ could enhance the removal of Cr(Ⅵ) via chemical reduction and physical adsorption,respectively. X-ray photoelectron spectroscopy(XPS) was used to analyze the mechanisms of Cr(Ⅵ) removal, which indicated that the ZⅥ loaded on the surface was oxidized, and the removed Cr(Ⅵ) was immobilized via the formation of Cr(III) hydroxide and Cr(III)–Fe(III)hydroxide/oxyhydroxide on the surface of EG-ZⅥ. | Congbin Xu Wenjie Yang Weijiang Liu Hongliang Sun Chunlei Jiao Ai-jun Lin | 2018 | Journal of Environmental Sciences2018，30，5： | 10 |

| 4 | Characterization and Methanol Adsorption of Walnutshell Activated Carbon Prepared by KOH Activation显示文摘Walnut-shellactivated carbons(WSACs)were prepared by the KOH chemicalactivation.The effects of carbonization temperature,activation temperature,and ratio of KOH to chars on the pore development of WSACs were investigated.Fourier transform infrared spectroscopy(FTIR),X-ray powder diffraction(XRD),and scanning electron microscopy(SEM)were employed to characterize the microstructure and morphology of WSACs.Methanoladsorption performance onto the optimalWSAC and the coal-based AC were also investigated.The results show that the optimalpreparation conditions are a carbonization temperature of 700 ℃,an activation temperature of 700 ℃,and a mass ratio of 3.The BET surface area,the micropore volume,and the micropore volume percentage of the optimalWASC are 1636 m^2/g,0.641 cm^3/g and 81.97%,respectively.There are a lot of micropores and a certain amount of meso-and macropores.The characteristics of the amorphous state are identified.The results show that the optimalWSAC is favorable for methanoladsorption.The equilibrium adsorption capacity of the optimalWSAC is 248.02mg/g.It is shown that the equilibrium adsorption capacity of the optimalWSAC is almost equivalent to that of the common activated carbon.Therefore the optimalWSAC could be a potentialadsorbent for the solar energy adsorption refrigeration cycle. | 余琼粉 李明 ji xu qiu yu zhu yuntao leng congbin | 2016 | Journal of Wuhan University of Technology(Materials Science)2016，31，2： | 3 |
| 5 | COMPARISON OF SIMULATING MINERAL DUST AEROSOLS IN EAST ASIA BY TWO EMISSION SCHEMES显示文摘Two common surface-dust emission schemes using critical wind speed and friction velocity were com-pared with the regional climate model RegCM3 in East Asia. In the comparison, transport of mineral dust and its distri-bution were simulated from March to April, 2001. Simulation results were also compared with TOMS aerosol index, showing that obvious differences exist in dust emission quantity and its column burden simulated by the dust emission schemes of friction velocity and wind speed criteria. The results obtained by the wind speed criterion are higher than that by friction velocity, bringing forth the problem whether or not the dust emission scheme matches the model. The obvious difference in the two schemes also explains the uncertainty of simulating mineral dust aerosol by modeling. | Jian Wu Yanyan Xu Congbin FU Renjian Zhang Min Dai Yong Zhu | 2006 | China Particuology2006，4，6： | 2 |
| 6 | A new index to describe the tropical Asian summer monsoon显示文摘We define a new monsoon index (MV) as the product of relative vorticity and equivalent potential temperature using the long-term NCEP/NCAR reanalysis data. The MV index provides new insights into the intraseasonal and interannual variabilities of the broad-scale tropical Asian summer monsoon (TASM), including the South Asian summer monsoon (SASM) and the South China Sea summer monsoon (SCSSM). On the intraseasonal timescale, the pentad-to-pentad MV index bears a close relationship to the broad-scale rainfall in the TASM regions. Among 29 summers from 1979 to 2007, in 23/27 summers the correlation coefficients are higher than 0.7 in the SASM/SCSSM region. However, in fewer than 9 summers, the correlations between the broad-scale rainfall and the existing circulation indices are higher than 0.7. On the interannual timescale, various existing SASM circulation indices are moderately or well correlated with all-India summer monsoon rainfall, whereas their correlations with broad-scale SASM rainfall are weak. In contrast, the summer mean MV index correlates well with the broad-scale SASM rainfall and all-India summer monsoon rainfall (correlation of 0.73 and 0.65, respectively). In the SCSSM region, the summer mean MV index also bears a close relationship to the SCSSM rainfall, although some discrepancies exist during certain years. The composite strong TASM shows a stronger low-tropospheric low pressure in association with the enhanced westerly winds and moisture transfer, stronger convection, and upper-tropospheric easterly winds, which indicate that the MV index can well capture the features of TASM. | ZhongFeng Xu CongBin Fu YongFu Qian | 2009 | Science China Earth Sciences2009，52，6： | 2 |

| 9 | Simulation of the direct effects of dust aerosol on climate in East Asia显示文摘The results from some general circulation models show distinct radiative forcing(RF) by dust aerosol,which potentially has an effect on climate change.The direct RF and regional climatic effects of dust aerosol over the East Asian region are investigated in this study using NCAR's Community Atmospheric Model version 3.1.The negative RF at the top of the atmosphere(TOA) and the surface(SRF) has been revealed except for some high-albedo regions,which leads to a decrease in the surface air temperature and brings an increase of atmospheric radiative heating under both clear-and all-sky conditions.The decrease in the surface air temperature can be found over a wide region that includes the Indian peninsula and northwest China.It accompanies an increase in eastern China and the Korean peninsula,and temperature changes are not limited to regions with a large dust optical depth.A belt of vapor increase is revealed from the Indian peninsula extending east to northern China,while vapor content evidently deceases in southwest China.An increase in precipitation can also be found in the belt of increased vapor accompanying the reduction of precipitation across the regions to the south of 30oN.The pattern of rainfall change helps to offset the trend of increasing wetness in the south and increasing dryness in the north of China in recent years. | Jian Wu Congbin Fu Zhiwei Han Jianping Tang Yanyan XU Renjian Zhang | 2010 | Particuology2010，8，4： | 1 |
| 10 | Global and Regional Impacts of Vegetation on the Hydrological Cycle and Energy Budget as Represented by the Community Atmosphere Model (CAM3)显示文摘The effects of vegetation and its seasonal variation on energy and the hydrological cycle were examined using a state-of-the-art Community Atmosphere Model (CAM3). Three 15-year numerical experiments were completed: the first with realistic vegetation characteristics varying monthly (VEG run), the second without vegetation over land (NOVEG run), and the third with the vegetation characteristics held at their annual mean values (VEGMEAN run). In these models, the hydrological cycle and land surface energy budget were widely affected by vegetation. Global-and annual-mean evapotranspiration significantly increased by 11.8% in the VEG run compared with the NOVEG run, while runoff decreased by 13.2% when the realistic vegetation is incorporated. Vegetation plays different roles in different regions. In tropical Asia, vegetation-induced cooling of the land surface plays a crucial role in decreasing tropical precipitation. In middle latitudes and the Amazon region, however, the vegetation-induced increase of evapotranspiration plays a more important role in increasing precipitation. The seasonal variation of vegetation also shows clear influences on the hydrological cycle and energy budget. In the boreal midhigh latitudes where vegetation shows a strong seasonal cycle, evapotranspiration and precipitation are higher in the summer in the VEG run than in the VEGMEAN run. | XU Zhongfeng ZENG Gang FU Congbin | 2009 | Atmospheric and Oceanic Science Letters2009，2，2： | 1 |

| 16 | Assessing the Performance of a Dynamical Downscaling Simulation Driven by a Bias-Corrected CMIP6 Dataset for Asian Climate显示文摘In this study,we aim to assess dynamical downscaling simulations by utilizing a novel bias-corrected global climate model(GCM)data to drive a regional climate model(RCM)over the Asia-western North Pacific region.Three simulations were conducted with a 25-km grid spacing for the period 1980–2014.The first simulation(WRF_ERA5)was driven by the European Centre for Medium-Range Weather Forecasts Reanalysis 5(ERA5)dataset and served as the validation dataset.The original GCM dataset(MPI-ESM1-2-HR model)was used to drive the second simulation(WRF_GCM),while the third simulation(WRF_GCMbc)was driven by the bias-corrected GCM dataset.The bias-corrected GCM data has an ERA5-based mean and interannual variance and long-term trends derived from the ensemble mean of 18 CMIP6 models.Results demonstrate that the WRF_GCMbc significantly reduced the root-mean-square errors(RMSEs)of the climatological mean of downscaled variables,including temperature,precipitation,snow,wind,relative humidity,and planetary boundary layer height by 50%–90%compared to the WRF_GCM.Similarly,the RMSEs of interannual-tointerdecadal variances of downscaled variables were reduced by 30%–60%.Furthermore,the WRF_GCMbc better captured the annual cycle of the monsoon circulation and intraseasonal and day-to-day variabilities.The leading empirical orthogonal function(EOF)shows a monopole precipitation mode in the WRF_GCM.In contrast,the WRF_GCMbc successfully reproduced the observed tri-pole mode of summer precipitation over eastern China.This improvement could be attributed to a better-simulated location of the western North Pacific subtropical high in the WRF_GCMbc after GCM bias correction. | Zhongfeng XU Ying HAN Meng-Zhuo ZHANG Chi-Yung TAM Zong-Liang YANG Ahmed M.EL KENAWY Congbin FU | 2024 | Advances in Atmospheric Sciences2024，41，5： | 0 |
