How is polyaluminum chloride (PA) made?

Method for producing polyaluminum chloride from hydrogen chloride waste gas and aluminum salt water waste liquid generated from anthraquinone synthesizing production CN106517288A(en)

Can polyaluminum chloride be used in water treatment?

In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.

What is polyaluminium chloride?

Polyaluminium chloride is prepared from aluminum hydroxide, calcium aluminate powder and industrially synthesized hydrochloric acid as main raw materials.

Can PAC be prepared from aluminum chloride solution?

PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [16, 21], sodium hydroxide [, , ] and sodium aluminate .

How much sulphate is added to a polyaluminium chloride reaction?

A process according to claim 10, characterised in that the reaction mixture is supersaturated into the metastable region, and the added amount of sulphate to the reaction mixture is kept belowabout 1.0 weight percent, calculated on the total weight of the produced polyaluminium chloride solution.
