polyaluminium chloride (PAC) for water treatment

Used in deodorant, in removing fluoride, aluminum, chromium, oil, with the exception of turbidity..
Polyaluminium Chloride is PAC for short.It is a kind of water-soluble inorgani polymers with high molecular weight .The structural formula is [AL2( OH) nCL6- nLm] ,in which the m represents the degree of polymerization, the n means neutral degree of PAC.The product is the yellow or thin yellow, deep brown, charcoal gray resin form solid.This product has stronger function of absorbing .In water solving process, some physical and chemical processes occurs accompanyingly such as coagulate, adsorbing, precipitation and ect.
