摘　　要：研究了用离子色谱法测定高效聚合氯化铝（PACS）中SO的方法。用离子交换法去除Al3+等金属离子，利用HCl和H2SO4的沸点差去除Cl-，然后用离子色谱法测定PACS中的SO。样品测定结果令人满意。A method for the determination of sulfate ions in high performance polymeric aluminium chloride by ion chromato graphy is investigated. Polyvalent metallic ions such as Al3+ are removed by ion exchange column and Cl- are removed by using boiling point difference between HCl and H2SO4 . The results are satisfactroy.
