  • 摘要: 采用电混凝技术对水中锑污染物进行处理，利用阳极电解铁板产生亚铁和三价铁离子，通过絮凝与共沉淀作用去除Sb（Ⅲ）和Sb（V）污染物，并详细探讨了电流密度、溶液初始pH、电解质离子及通入N2对锑去除效率的影响。结果发现，锑初始浓度为1 mg/L时，反应30 min后Sb（Ⅲ）浓度低于5.0 μg/L，Sb（V）浓度为28.1 μg/L，表明Sb（Ⅲ）去除效率明显优于Sb（V）。另外，研究发现，电流密度及初始pH对Sb（Ⅲ）的去除效率影响较小，增大电流密度会提高Sb（V）去除效率，溶液初始pH为4.5时Sb（V）去除效率最高；Mg2+与HCO3-有助于Sb（V）的去除，Ca2+、SiO32-和PO43-对Sb（V）的去除有一定的抑制作用；通入N2会提高Sb（V）的去除率。
    Abstract: Removal of antimony (Ⅲ) and antimony (V) contaminant in water by electrocoagulation process was investigated.The effects of current density,initial pH value,different coexisting ions and ventilation with nitrogen on the removal efficiency of antimony were investigated.The results indicated that the final concentrations of antimony (Ⅲ) and antimony (V) were lower than 5.0 μg/L and 28.1 μg/L after 30 minutes,showing that the removal efficiency of antimony (Ⅲ) was significantly better than antimony (V).The current density and initial pH value have small effects on antimony (Ⅲ) removal,however,increasing the current density significantly improves the removal efficiency of antimony (V),the antimony (V) removal efficiency is highest when the initial pH value is 4.5. Mg2+ and HCO3-promote antimony (V) removal. Ca2+,SiO32-and PO43- inhibit antimony (V) removal. Ventilation with N2 improves the removal rate of antimony (V).
