摘　　要：介绍了用氧化剂和高温处理制取含碱性表面基团活性炭的方法 ,测定了它们的离子交换容量。研究了溶液pH和Cr(Ⅵ )的初始浓度对Cr(Ⅵ )去除率的影响。讨论了含碱性表面基团活性炭对溶液中Cr(Ⅵ )The preparation of activated carbon containing basic surface radical with oxidant and at under high temperature is introduced. The ion exchange capacity of modified activated carbon are determined. The effects of chemical factors such as pH and concentration of hexavalent chromium are investigated. The removal mechanism of hexavalent chromium by modified activated carbon is discussed.
