Polyaluminium Chloride

Polymerized aluminum chloride (PAC) is an inorganic material, an emerging water purification material, inorganic polymer coagulant, referred to as polyaluminum. It is a water-soluble inorganic polymer between AlCI₃ and Al(OH)₃, with the chemical formula [Al₂(OH)nCl₆-n]m, where m represents the degree of polymerization, and n indicates the degree of neutrality of the PAC product. n=1~5 is a highly charged polymerized cyclic chain with the Keggin structure, which has a high degree of electro-neutralization and bridging effect on colloid and particulate matter in water, and can It can strongly remove microtoxic substances and heavy metal ions, with stable properties.
