摘要
生产氯化钙的原材料进卤液是生产纯碱的废液,此液中含有硫酸根离子,导致成品氯化钙中含有硫酸根离子,有些用户要求硫酸根离子含量。本人通过大量试验证明重量分析法对氯化钙中硫酸根离子的测定,结果比较准确,实验条件好掌握。
The original material which produces calcium chloride＇s entering a Lu liquid is to produce a discard of pure alkali liquid, there is sulfuric acid root in this liquid ion, cause to have in the finished product calcium chloride sulfuric acid root ion, have some customers to request a sulfuric acid root an ion content, Itself pases to great quantities experiment a certificate weight analysis a method to the measurement of sulfuric acid root ion in the calcium chloride, as a result more accurate, test a condition to control SO.
