摘要
在盐酸的介质中，钡离子与硫酸根离子生成难溶解的硫酸钡，使溶液混浊，采用乙醇作稳定剂，利用分光光度计进行比色，可测定氧化铁中的硫酸根。
In the hydrochloric acid medium, barium ion and the sulfate radical ion produce barium sulfate, which is difficult to dissolve to make the solution comuddy, with alcohol as stabilizers, making use of the spectral photometer to carry out a colorimetric, to determine sulfuric acid in the ferric oxide.
