Abstract

Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed. This paper presents a novel method to prepare high-purity PACl which contains high aluminum oxide content (>10%), high basicity (>90%), and low insoluble substance (
