Arsenic(III) Remediation from Contaminated Water by Oxidation and Fe/Al Co-Precipitation
Manganese Oxides Iron Hydroxides Arsenic Remediation Fe/Al Coagulants Contaminated Water
2013/3/20
Battery grade γ-MnO2 powder was investigated as an oxidant and an adsorbent in combination with Fe/Al coagulants for removal of arsenic from contaminated water. Simultaneous oxidation of As(III) and r...
Ca+催化的N2O+CO反应机理的理论研究
2O 金属阳离子 反应机理 密度泛函理论
2013/7/11
采用B3LYP/cc-pVTZ理论水平系统研究了Ca+离子催化N2O+CO→N2+CO2反应的微观机理.反应分两步进行:第一步Ca+夺取N2O中的O原子有两条反应通道,其中优势通道为Ca+金属离子与N2O分子中O作用,形成线性分子复合物,活化N2O分子中的N—O键,之后的反应路径为O—N键断裂机理;第二步为CaO+金属氧化物阳离子与CO反应,反应过程遵循插入消去机理.纵观整个Ca+金属离子催化过程...
