浅谈镍铜铁的化学物相分析

The brief discussion on phases of chemical analysis in Ni, Cu and Fe

物相分析方法分为物理物相分析和化学物相分析，化学物相分析利用各种物相在化学溶剂中的溶解度和溶解速度的差异，选择溶解测定某一元素的分别含量。我国的化学物相分析工作发展迅速，在各个领域都有所应用，本文对化学物相分析中的镍铜铁化学物相分析进行简要介绍。镍化学物相分析内容包括硫酸镍、氧化镍、硫化镍、硅酸镍及全镍的测定。铜化学物相分析内容包括自由氧化铜、结合氧化铜、次生硫化铜、原生硫化铜、硫酸铜及总铜。铁化学物相分析内容包括磁性铁、碳酸铁、赤褐铁、硅酸铁、黄铁矿和全铁的测定。

The Phase of analysis method is divided into the phase of physical analysis and the phase of chemical analysis, the phase of chemical analysis used the differences of different phases＇ solubility and dissolved rate in the chemical solvents, dissolved and measured the respective content of an element selectively. China＇s chemical phase analysis work has developed rapidly and has been applied in various fields, this paper will appear a brief introduction on phases of chemical analysis in Ni, Cu and Fe. The phase of chemical analysis in Ni includes nickel sulfate, nickel oxide, nickel sulfide, nickel silicate and the determination of nickel. The phase of chemical analysis in Cu includes free copper oxide, combined with copper oxide, secondary copper sulfide, primary copper sulfide, copper sulfate and copper. The phase of chemical analysis in Fe includes magnetic iron, ferric carbonate, red limonite, iron silicate, pyrite and the determination of all iron.
