摘要
毒砂是一种含有有毒元素的矿物,在氧化和酸性的介质中很容易被氧化和分解,对环境造成污染。研究毒砂氧化作用的速率和影响因素,有利于环境保护。本文介绍了用混合流反应器研究毒砂氧化作用的方法。指出用Fe-2(SO-4)-3作氧化剂氧化毒砂所释放的砷以As(Ⅲ)为主。
Arsenopyrite is one of the minerals containing toxic elements, which is easily oxidized and decomposed in oxidative and acidic conditions. It is closely related with environmental contamination. Research on the oxidation r ate and factors controlling the oxidation of arsenopyrite is helpful for environ mental protection. This paper introduces a method of studying the oxidation of a rsenopyrite with a mixed flow reactor, and points out that As (Ⅲ) is a major sp ecies of arsenic released from oxidation of arsenopyrite with Fe-2(SO-4)-3 as oxidant.
