| 摘 要： | 为了研究阳离子存在对零价铁去除水体中铬污染的影响,在实验室条件下,通过批次实验考察了零价铁在Ca2+、Mg2+单独存在及共存时去除水体中铬污染的效果。结果表明:Ca2+,Mg2+单独存在及共存时,零价铁都可以有效去除水体中的铬污染。前者促进作用不明显,后者促进作用较大。二者共存也可以促进零价铁去除水体中铬污染,且促进作用高于二者单独存在体系。

| Abstract: | In order to study the impact of cations on remediation of cr-polluted water by zero-valent iron , the chromium removal ratio by zero-valent iron in Ca2＋ ,Mg2＋ ,and Ca2＋ ＋Mg2＋ existing systems are test-ed respectively .T he results show chromium is removed effectively by zero valent iron in Ca 2＋ ,Mg2＋ and Ca2＋ ＋Mg2＋ existing systems .T he chromium removal ratio is increased a little by zero-valent iron in Ca2＋＋Mg2＋ existing system ,and Mg2＋ greatly enhanced remediation .Ca2＋ ＋ Mg2＋ plays a promotion role in Cr removal .Its promotion is the most significant . |
