六价铬具有毒性大，能在水生生物和农作物内富集，通过食物链被人体吸收并在体内积累, 到一定程度便会致病，甚至引起癌症。含铬废水是当今国际上公认的最严重的公害之一，国家环保局早已把含铬废水列为治理的重点。含铬废水主要来自电镀、制革、采矿和染料等工业生产。铬污染的不断加剧给人类健康和环境造成了极大的危害，引起一系列环境污染问题。所以有效处理含铬废水一直是工业生产中亟待解决的问题之一，目前处理含Cr(Ⅵ)废水的方法主要有两大类：一类是还原法。这类方法在处理过程中产生大量污泥，容易产生二次污染。第二类是直接处理Cr(Ⅵ)。离子交换法是这类方法中的一种，具有效率高，运行费用低，无二次污染等优点，受到广泛的关注[1-10]。本文研究了D318树脂（功能基为：-CH2NH2）对水中Cr(Ⅵ)的吸附行为和机理。结果表明，D318树脂具有合成成本低，工艺流程简单，吸附容量大且易解吸等优点。试验结果为D318树脂在处理含铬废水中的应用提供了理论依据。

Hexavalent chrome has a severe toxicity, and can gather in water living creatures and farm crops, and is absorbed by the human body through vegetative chain and accumulate inside the body, causing disease even cancer when reaching certain degree.Chrome contained waste water is nowadays internationally accepted as one of the most serious harmful effectses.The national environmental protection bureau has already listed chrome contained waste water as focal point of controlling.Chrome contained waste water mainly come from production such as electroplate, tanning, mining and dyestuff etc..The continuous aggravating of the chrome pollution will do harm to mankind health and environment , causing problems of pollution of the environment .So the valid processing of chrome contained waste water is always a burning question to industrial production.currently there are mainly two major types of ways to treat the Cr(Ⅵ ) contained waste water :One type is a Reduction Method.This method will create great quantities of dirty mire in the process, easily causing secondary pollution.Another type is direct processing of Cr(Ⅵ ).The ion exchanging method is one kind of the method, having advantages of high efficiency and low operation expenses ,and no secondary pollution etc, and is subject to extensive concern[1-10].This text studies the adsorption and mechanism of D318 resins(functional group:-The CH2 NH2) of Cr(Ⅵ ) in the water.The result shows D318 resins have advantages of low synthetic cost, simple process flow and great capacity of absorbtion and the easy desorption etc. .Experiment results provided theories basis for D318 resins's application in treating chrome contained waste water.
