摘要
在盐酸介质中 ,钡离子与硫酸根离子生成难溶的硫酸钡 ,使溶液混浊 ,采用乙醇作稳定剂 ,利用分光光度计进行比色 ,可测定氧化铁中硫酸根。该法手续简便 。
In hyarochloride medium,barium ion reacts chemically with sulfate radical ion to produce barium sulfate which is defficuulty to solve and do turbidity to solution.Taking on alcohol as stabilizer,using spectrophotometer to do colorimetric analysis the sulfate radical in iron oxide can be determined.This method has the characters of convenient operation and high accuracy.
