The results suggest that the C-S-H/calcite interface is relatively strong......
, Shenyang 110004, China) Abstract: The study on arsenopyrite and realgar of bacterial oxidation shows that the chemical behaviors of different arsenic-bearing sulphides oxidated by thermophilic bacteria are quite distinct. Arsenopyrite is active and quickly eroded in bacteria-bearing solution. With a high leaching rate over 95%, the arsenopyrite phase cannot be detected by X-ray diffraction(XRD......
Treatment of simulated wastewater from in situ ching uranium mining byzerovalent iron and sulfate ducing bacteria YI Zheng-ji(易正戟)1, 2, LIAN Bin(连 宾)1, YANG Ying-qun(杨颖群)2, ZOU Jian-ling(邹建陵)2 1...) and sulfate reducing bacteria (SRB) can function synergistically and accelerate pollutant removal. Batch experiments suggest that combining ZVI with SRB can enhance the removal of U(Ⅵ) synergistically......
