    试翻译一下 电镀、制革、采矿和染料等工业生产中产生大量含铬废水，引起一系列环境污染问题。六价Cr的毒性大,易于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; 因此，含铬废水被公认为当今最严重的公害之一, 国家环保局早已把含铬废水列为治理的重点。
    所以, 分离含铬废水中的铬对于环境保护和人类健康都有非常重要的意义。 Massive volume of waste water containing chromium is generated during the production of electroplating, leather making, orc mining and dyeing, and this causes series of pollution problem。
     The 6-valence Cr is of great toxic and can be easily absorbed by human body and be accumulated inside, which would cause sickness and even cancer。
     Thus, chromium-contained water is considered as one of the most serious environmental pollution。
   It has been listed as a major task by the National Environment Protection Bureau(?not sure about the name), and it's very much meaningful for environment protection and human hygene to separate chromium from so-contained water。
     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[2 ] ；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，再生的料液能循环被加以利用等优点，受到广泛的关注[1-7]。
    本文研究了XSD-296树脂对铬(Ⅵ)的吸附性能，结果表明，XSD-296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，在含铬(Ⅵ)废水的处理中有一定实际应用价值。
  红外光谱分析表明,离子交换过程形成了配位化合物 Currently there're 2 major methods to tackle the CrVI-contained water: a)the reduction system, however, it emerges massive polluted earth while proceding and causes re-pollution easily; b)direct CrVI treatment, among them the ion exchange system is of high effeciency and the re-produce can be reusable, and therefore the system is popularily interested[1-7]。
     This article discusses about the CrVI adsorption capability of the XSD-296 resin and the result indicates that it's practically appliable to use XSD-296 resin to tackle CrVI-contained water with the advantages of low cost, simple process, huge absorption volume and easy de-absorption。
     Infra spectrum analysis shows that matching chemical compound(? not sure about this name) is generated during ion exchange process。
     化工文章真累人啊！！呵呵 。
