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＋、M g2＋单独存在及共存时去除水体中铬污染的效果。结果表明：Ca2＋，M g2＋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。

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 .
