| 摘 要： | 本文以泰安市一处多年前受电镀铬严重污染地区为研究对象,对比研究六价铬在不同岩土中吸附、转化及迁移的特征和规律,铬易在水土共存的含水层中富集,并可转移到地下水中.土壤中三价铬可引起潜在的危害.水体中六价铬在富氧的情况下是稳定的,并能维持一个较长的时期.铁盐是一种较好的除铬剂,可以有效地去除水中六价铬离子,从而提高了地下水的利用价值.

| Abstract: | The paper demonstrates releasing law of chromium compounds in soil polluted by chrominm a few years ago in Taina. Chromium compounds are easily accumulated in aquifer. Soil polluted by chromium can dissolye again and lead to groundwater pollution. Cr3 + in soil may cause potential pollution in the long run under the condition of oxidizing environment. Ferrous compounds can be removed Cr6 + efficiently. The efficiency to remove chromium is very high, so water quality is improved. |
