摘要
本文研究了有机酸在化学物相分析中的应用问题.通过对其酸效应影响的探讨,证明CH_8COOH-CH_8COONa—H_2O_2溶液(pH～4.5)是硫化铁矿物有效的选择性溶剂.其主要特点是共存的铁绿泥石、铁橄榄石等易溶性硅酸铁矿物均不干扰.方法用于铁矿石中硫化铁的分离测定,结果比较满意.
The influences of acid effect of organic acid on the selectivity of dissolvent have been discussed in this paper.It is proved that HAc-NaAc-H2O2 solution is the effectively selective dissolvent for minerals of ferrous ( ferric ) sulfides. It is the main characteristic, the associated minerals of dissolvable ferrous silicates ( chlorite, olivine etc ) don't interfere. The method has been applied to separate and determine the minerals of ferrous ( ferric ) sulfidej in iron ores with satisfactory results.
