| 1 | The subducted slab of Yangtze Continental block beneath the Tethyan orogen in western Yunnan显示文摘The western Yunnan area is a natural laboratory with fully developed and best preserved Tethyan orogen in the world. Seismic tomography reveals a slab-like high velocity anomaly down to 250 km beneath the western Yunnan Tethyan orogen, to its west there is a low-velocity column about 300 km wide. in the region from Lancangjiang to Mojiang an obvious low velocity in the lower crust and uppermost mantle overlies on the slab. Synthesizing the available geological and geochemical results, the present paper demonstrates that this slab-like high velocity anomaly is a part of the subducted plate of Yangtze Continental segment after the closure of Paleotethys. The collision of India and Eurasia continent starting from 50-60 MaBP might trigger thermal disturbance in the upper mantle and cause the uprising of asthenosphere, in that case the subducted Yangtze plate could be broken off, causing Cenozoic magmatic activities and underplating in the Lancangjiang-Mojiang region. | Futian Liu Jianhua Liu Dalai Zhong Jiankun He Qingyu You | 2000 | Chinese Science Bulletin2000，45，5： | 28 |
| 2 | Study of ciprofloxacin removal by biochar obtained from used tea leaves显示文摘In this study,used tea leaves(UTLs) were pyrolyzed to obtain used tea-leaf biochar(UTC),and then the UTC was used as an adsorbent to remove ciprofloxacin(CIP) from aqueous solutions.Batch experiments were conducted to investigate the CIP adsorption performance and mechanism.The results showed that the CIP-adsorbing ability first increased and then declined as the UTC pyrolysis temperature increased.The UTC obtained at 450°C presented excellent CIP-absorbing ability at p H 6 and 40°C.The maximum monolayer adsorption capacity was 238.10 mg/g based on the Langmuir isotherm model.The pseudo-second-order kinetic equation agreed well with the CIP adsorption process,which was controlled by both external boundary layer diffusion and intra-particle diffusion.The characterization analysis revealed that the \OH groups,C_C bonds of aromatic rings,C\H groups in aromatic rings and phenolic C\O bonds play vital roles in the CIP adsorption process,and that the N\C,N\O,O\C_O and C\OH groups of UTC were consumed in large quantities.π–π interactions,hydrogen bonding and electrostatic attraction are inferred as the main adsorption mechanisms.The present work provides not only a feasible and promising approach for UTLs utilization but also a potential adsorbent material for removing high concentrations of CIP from aqueous solutions. | Jie Li Guangwei Yu Lanjia Pan Chunxing Li Futian You Shengyu Xie Yin Wang Jianli Ma Xiaofu Shang | 2018 | Journal of Environmental Sciences2018，30，11： | 5 |
