摘要
提出了以乙醇为介质，钍试剂作指示剂，亚甲基蓝溶液作衬色剂，用氯化钡标准溶液作滴定剂，测定水样中硫酸根离子的方法。该方法可简便。
A method for the determination of sulfate in water is established by using alcohol as the medium, thoron I as the indicator, methylene blue solution as the foil and barium chloride standard solution as the titrant. The method has been used successfully for the determination of sulfate in water and is characterised by its simplicity and accuracy.
