摘　　要：以铝矾土为原料,用酸溶出法制取净水剂聚硫氯化铝(PACS).研究了盐酸、硫酸用量及加热时间对铝矾土中铝的溶出影响,并讨论了硫酸对溶出液中AlCl3结晶的影响.The paper puts forward a new preparation method of PACS with Alumina by acid dissolution, which is used as a effective water treatment agent. Several quantities that affect the quality of PACS are evaluated, such as the quantity of acid, concentration and polymerization time. The most favorable experimental conditions for the preparation of PACS are studied.
