采用白腐菌和纳米零价铁（nZVI）联合体系强化去除水中Cd（II），并考察pH、Cd（II）初始浓度、温度、nZVI投加量对Cd（II）去除的影响，分析nZVI对白腐菌胞内外富集镉的影响特性，同时结合扫描电镜、红外光谱、X射线光电子能谱、三维荧光光谱等手段分析联合体系对Cd（II）的强化去除机制.结果表明，在pH=6，Cd（II）初始浓度为50mg·L-1，温度为30℃，nZVI投加量为0.1g·L-1的条件下反应180min后，Cd（II）的去除率可达到99.5%以上.联合体系对Cd（II）的去除过程符合准二级动力学，主要去除机制为白腐菌对Cd（II）的胞外络合吸附，添加nZVI能促进白腐菌对Cd（II）的胞外吸附，FTIR和XPS分析表明...

A combined system of white rot fungus and nanoscale zero-valent iron(nZVI) was used to enhance the removal of Cd(Ⅱ)from water. The effects of pH, Cd(Ⅱ) initial concentration, temperature and nZVI dosage on Cd(Ⅱ) removal were examined, and the impact of nZVI on intracell...MORE A combined system of white rot fungus and nanoscale zero-valent iron(nZVI) was used to enhance the removal of Cd(Ⅱ)from water.
