| 主权项 | 1. Polyaluminum chlorosulfate (PACS) having a basicity of 55 to 75% and formula (I): Al(OH)xCl(3-x-2y)(SO4)y (I) wherein 1.78<x<2.02, 0.03<y<0.45, and 1.8<x+y/2<2.1; Al:SO4=2 to 34; Al:Cl=0.9 to 3.0, Al:OH=0.5 to 0.6; and the average molecular weight of the PACS is greater than or equal to 95 and less than or equal to 111, and wherein salts present in the PACS comprise 0-1.0% sodium chloride by weight and 0-1.0% sodium sulfate by weight. | ||
