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)

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 .

Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

What are the synthesis parameters of aluminum chloride hexahydrate?

The synthesis parameters were concentration of aluminum chloride hexahydrate (0.4 to 0.8 M), basicity ratio (2.0 to 2.4), reaction temperature (60 to 80 °C) and time (180 to 360 min). The performance of PΑC for water treatment was also investigated. The monomeric, medium polymeric and colloidal species of PAC were determined by Ferron test method.
