Abstract:

According to the appearance of the polyaluminium chloride made from different materials containing 6% of water insoluable matter, compared with the analytical steps of the National Standard of it，GB 15892-1995，and combining with the actual case in the sample tests，a testing method，which is known as "setting at room temperature", for the determination of the basicity of polyaluminium chloride is put forward, in order to make the testing result accord with the fact better.

Key words: polyaluminium chloride, basicity, analysis

摘要：

根据不同原料生产的聚合氯化铝的外观,质量分数为0.6%水不溶物的状况,参照聚合氯化铝国家标准GB15892—1995的分析步骤,结合对样品的实际检测情况,提出用“室温放置法”,分析聚合氯化铝的盐基度,以便使分析结果更符合实际。
