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.

What is a polyaluminium chloride preparation method?

The invention relates to a polyaluminium chloride preparation method, which belongs to the chemical field. The polyaluminium chloride comprises the following components by weight: 100-120 parts of bauxite, 150-180 parts of 20-30% of hydrochloric acid, 60-80 parts of calcium aluminate and 20-30 parts of calcium carbonate.

What is the performance of synthesized PAC compared with aluminum sulfate?

The performance of synthesized PAC compared with aluminum sulfate, aluminum chloride and commercial PAC for water treatment. 4. Conclusion The synthesis of PΑC results revealed that the low concentration of aluminum chloride favored to the formation of Αl b species of PΑC and the high concentration preferred to the formation of Αl c species of PΑC.

How to prepare poly Aluminium chloride?

1. a preparation method for poly aluminium chloride, is characterized in that, by weight, comprises hydrochloric acid 150-180 part, calcium aluminate 60-80 part, calcium carbonate 20-30 part of bauxitic clay 100-120 part, 25-30%, comprises the following steps: (1), by bauxitic clay calcination 0.5-2h at 1200-1500 ℃, pulverize;

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 .
