| 1 | Seasonal and spatial distribution of ammonia-oxidizing microorganism communities in surface sediments from the East China Sea显示文摘Ammonia oxidation plays a significant role in the nitrogen cycle in marine sediments. Seasonal and spatial distribution of ammonia-oxidizing archaea(AOA) and betaproteobacteria(β-AOB) in surface sediments from the East China Sea(ECS) were investigated using ammonia monooxygenase α subunit(amo A) gene. In order to characterize the community of AOA and β-AOB, real-time quantitative polymerase chain reaction(q PCR) was carried out in this study, along with environmental parameters. The abundance of β-AOB amo A gene(2.17×106–4.54×107 copy numbers per gram wet weight sediment) was always greater than that of AOA amo A gene(2.18×105–9.89×106 copy numbers per gram wet weight sediment) in all sampling stations. The q PCR results were correlated with environmental parameters. AOA amo A gene copy numbers in April were positively related to temperature and nitrite concentration(p<0.05). β-AOB amo A gene copy numbers in August correlated negatively with salinity(p<0.01), and correlated positively with ammonium concentration(p<0.05). With the increase of salinity, the amo A gene copy ratio of AOB to AOA had a tendency to decrease, which suggested β-AOB dominated in the area of high level ammonium and AOA preferred high salinity area. | HE Hui ZHEN Yu MI Tiezhu LU Xinglan YU Zhigang | 2015 | Acta Oceanologica Sinica2015，34，8： | 3 |
| 2 | A hybrid monolithic column based on flower-shaped zeolitic imidazolate framework for efficient capillary microextraction of brominated flame retardants显示文摘A novel flower-shaped zeolitic imidazolate framework(ZIF) doped organic-inorganic hybrid monolithic column(ZIF-HMC) was prepared by a simple sol-gel 'one-step' method and utilized for efficient capillary microextraction(CME) of four brominated flame retardants.The prepared monolithic was characterized by Fourier transform infrared,scanning electron microscopy,X-ray photoelectron spectroscopy,energy disperse spectroscopy,and N_(2) adsorption-desorption.The parameters of CME were optimized by orthogonal array design.Under the optimal conditions,the ZIF-HMC showed excellent extraction efficiency,the limit of detection(LODs) and the limit of quantification(LOQs) were in the range of0.52$3.1 mg/L and 1.7$10 mg/L,respectively,and the proposed method demonstrated good recovery(88.8%–116.6%) with the RSD less than 13.6% and a reusability of at least 30 times.The ZIF-HMC possessed great potential for separating organic pollutants and the strategy used here could be extended to prepare other derivatized HMC functionalized monoliths. | Xuemei Wang Xinglan Cui Hong Ji Fangbing Wang Yacong Liu Xinzhen Du Xiaoquan Lu | 2021 | Chinese Chemical Letters2021，32，10： | 0 |
