Polyaluminum chloride (solid) 17 (inorganic compound)

Polyaluminum chloride(PAC)is an inorganic substance,an emerging water purification material,and an inorganic polymer coagulant,abbreviated as polyaluminum.It is a water-soluble inorganic polymer between AlCl3 and Al(OH)3,with a chemical formula of[Al2(OH)nCl6-n]m,where m represents the degree of polymerization and n represents the neutrality of the PAC product.N=1-5 are highly charged polymer cyclic chains with Keggin structure,which have high electrical neutralization and bridging effects on colloids and particles in water,and can strongly remove trace toxins and heavy metal ions,with stable properties.The inspection method can be carried out according to the national standard GB 15892-2003.Due to the bridging effect of hydroxide ions and the polymerization effect of multivalent anions,the produced polyaluminum chloride is an inorganic polymer water treatment agent with a relatively large molecular weight and high charge.
