锌精矿中锌的测定,口前多采用氢氧化物沉淀分离-EDTA滴定法,该法手续冗长。用EDTA直接滴定锌,需要克服多种元素的干扰。为此,前人作了不少工作,但消除锰的干扰问题没有得到好的解决。我们在株洲冶炼厂工作的基础上,针对锌精矿的分析要求进行了一些必要的条件试验,制定了锌精矿或类似样品中锌的直接络合滴定方法。本法基本上解决了锰的干扰,经应用于各种类型矿样的分析,准确度符合要求,操作较易掌握,4
Zinc concentrate zinc determination, the mouth of the more precipitation separation using-EDTA titration method, the procedure lengthy. Direct titration of zinc with EDTA, you need to overcome the interference of a variety of elements. For this reason, many predecessors have done a lot of work, but the problem of eliminating the interference of manganese has not been well resolved. Based on our work in Zhuzhou Smelter, we conducted some necessary conditions tests for the analysis of zinc concentrates and developed a direct complexometric titration method for zinc in zinc concentrate or similar samples. This law basically solved the interference of manganese, applied to the analysis of various types of mineral samples, accuracy meets the requirements, the operation easier to grasp, 4
