| 3 | Global DEMs vary from one to another:an evaluation of newly released Copernicus,NASA and AW3D30 DEM on selected terrains of China using ICESat-2 altimetry data显示文摘A good understanding of the quality of digital elevation model(DEM)is a perquisite for various applications.This study investigates the accuracy of three most recently released 1-arcsec global DEMs(GDEMs,Copernicus,NASA and AW3D30)in five selected terrains of China,using more than 240,000 high-quality ICESat-2(Ice,Cloud and land Elevation Satellite)ALT08 points.The results indicate the three GDEMs have similar overall vertical accuracy,with RMSE of 6.73(Copernicus),6.59(NASA)and 6.63 m(AW3D30).While the accuracy varies considerably over study areas and among GDEMs.The results show a clear correlation between the accuracy and terrain slopes,and some relationship between the accuracy and land covers.Our analysis reveals the land cover exerts a greater impact on the accuracy than that of the terrain slope for the study area.Visual inspections of terrain representation indicate Copernicus DEM exhibits the greatest detail of terrain,followed by AW3D30,and then by NASADEM.This study has demonstrated that ICESat-2 altimetry offers an important tool for DEM assessment.The findings provide a timely and comprehensive understanding of the quality of newly released GDEMs,which are informative for the selection of suitable DEMs,and for the improvement of GDEM in future studies. | Hui Li Jiayang Zhao Bingqi Yan Linwei Yue Lunche Wang | 2022 | International Journal of Digital Earth2022，15，1： | 1 |

| 5 | Effects of Solution Chemistry Conditions and Adsorbent Surface Properties on Adsorption of Ni(Ⅱ) on Laiyang Bentonite显示文摘The effects of solution chemistry conditions and adsorbent surface properties on the adsorption of Ni(II) on Laiyang bentonite were investigated via the batch technique. Potentiometric and mass titration techniques were employed in the batch experimental methods, and the results showed that the point of zero net proton charge(PZNPC) of bentonite at different ionic strength denoted p HPZNPC to be 8.2±0.1. The removal of Ni(II) from the solution increased with an increasing bentonite dosage, with the maximum removal efficiency equating up to 99%. The adsorption of Ni(II) on bentonite increased with an increasing p H value at a p H value of <8.5, and reached a Ni(II) removal efficiency of >99% at a p H value of >10.2. The Ni(II) adsorption performance exhibited different responses to cations(K+, Na+) but was not influenced by the background anions(NO3-, Cl-, and Cl O4-). The adsorption of Ni(II) was dominated by the outer-sphere surface complexation and ion exchange with Na+/H+ on bentonite surface at low p H value, whereas the inner-sphere surface complexation and surface precipitation were the main adsorption mechanisms at high p H value. The adsorption isotherms of Ni(II) on bentonite can be described well by the Langmuir model. The thermodynamic parameters of adsorption, including the Gibbs free energy, the enthalpy change, and the entropy change, at different temperatures indicated that the adsorption of Ni(II) on bentonite was endothermic and spontaneous. | Cao Xiaoqiang Yan Bingqi Xue Jianliang Wang Qian Wang Yaping Huang Yongqing Zhang Yan Lyu Xianjun | 2016 | China Petroleum Processing & Petrochemical Technology2016，18，3： | 0 |
