黄铁矿单矿物分析

Pyrite Analysis

黄铁矿常规分析多采用单独取样,针对某些元素采用有关分析方法。因而手续较繁琐,需要样品量也大。为了简化分析流程,减少样品用量,经试验拟定了黄铁矿单矿物系统分析流程。其特点是在一分称样中通过阳离子交换树脂分离,使阴阳离子分成两部分。在含阴离子溶液中可测定硫、砷、硒、磷等元素;在含阳离子溶液中可测定铁、铜、锌、镉、钴、镍、锰、锢、钙、镁等元素。解决了黄铁矿单矿物主要项目的测定。

A sample solution in 0.2 N hydrochloric acid was passed through a cations exchange column. The cations such as Fe, Cu, Cd,Zn, Co, Ni, Mn, In, Ca and Mg were quantitatively separated from S, As, P, Se and etc. 2 N hydrochloric acid was selected to eluate the above metals. The metals were determined by aas, spectrophotometry, polarography and induced colonmetric method separately.
