摘要
针对测定含有Cu2+、Fe3+、Zn2+、Co2+等金属离子溶液中游离硫酸的影响因素,试验了用亚铁氰化钾沉淀分离干扰金属离子,消除其对游离硫酸测定的影响。试验取得了满意的结果,并拟定出了可靠的酸性溶液中游离硫酸测定方法。
Aimed at the influential factors of Cu^(2+),Fe^(3+),Zn^(2+),Co^(2+) and other metallic ion solutions in free sulfuric acid determination,the ferro potassiumcyanide is used for precipitating interferential metallic ions so as to eliminate their effect on free sulfuric acid determination.The test result is proved to be successful.Based on this,the determination procedures for determination of free sulfuric acid in acid solution has been drawn up.
