Poly Aluminum Chloride

Polyaluminum chloride (PAC), abbreviated as polyaluminum, is a water-soluble inorganic polymer between AlCl3 and Al (OH) 3. Its chemical formula is [Al2 (OH) nCl6-n] m, where m represents the degree of polymerization, n represents the neutrality of PAC products, and n=1-5 are high charge polymer chains with Keggin structure. PAC has a high degree of electrical neutralization and bridging effect on colloids and particles in water, and can strongly remove toxic substances and heavy metal ions. Its properties are stable and it is often used as an emerging water purification material and coagulant. It is widely used in the purification treatment of drinking water, industrial wastewater, and urban sewage
