重有色金属化学分析中的化学分离问题研究

Research on Chemical Separation in Chemical Analysis of Heavy Nonferrous Metals

在自然界中,绝大多数的重有色金属物质都是以混合物的矿石状态形式存在,人们进行化学实验分析时,选取应用某种重有色金属物质材料,依据它的混合物是无法认识该物质的物理性质、化学性质,从而影响重有色金属的正确使用,不能更好地发挥金属物质的积极作用。所以,从化学实验分析的需要方面考虑,重有色金属的分离和提纯非常重要。本文结合工作实践经验和参考相关文献对重有色金属化学分析中的化学分离问题进行探讨。

In nature,the vast majority of heavy non-ferrous metal substances exist in the form of mixtures of ore.When people conduct chemical experiment analysis,they choose to use a certain heavy non-ferrous metal material.According to its mixture,the substance cannot be recognized.The physical and chemical properties of heavy non-ferrous metals affect the correct use of heavy non-ferrous metals,and the positive effects of metal substances cannot be better played.Therefore,considering the needs of chemical experiment analysis,the separation and purification of heavy non-ferrous metals is very important.This article discusses the problem of chemical separation in the chemical analysis of heavy non-ferrous metals based on practical experience and reference to related literature.
