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 a mineral that contains toxic elements and is easily oxidized and decomposed in oxidizing and acidic media, contaminating the environment. Studying the rate and influencing factors of arsenopyrite oxidation is beneficial to the environmental protection. This article describes a mixed-flow reactor for the study of arsenic oxidation method. It is pointed out that As (Ⅲ) is the main arsenic released from the oxidation of arsenopyrite with Fe-2 (SO-4) -3 as oxidant.
