摘要： Novel basic aluminum chlorosulfate solutions, having a basicity ranging from 45% to 70% and wherein more than 80% of the SO.sub.4.sup.2- values are complexed, prepared, e.g., by reacting calcium carbonate with a chlorosulfuric solution of aluminum, are useful coagulating and flocculating agents for the removal of impurities from aqueous media, notably to prepare potable water therefrom; the water thus treated contains but trace amounts of residual aluminum values.
