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.

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 .

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 .

Does initial concentration of aluminum chloride affect the yield of Al B?

As observed in Fig. 1 (a–d), the effects of initial concentration of aluminum chloride, basicity ratio, reaction temperature and time curves were steep slope and curvature, which revealed that the yield of Al b content in the PΑC species was very sensitive for these factors.

Is Pac better than aluminum sulfate & aluminum chloride for removing turbidity & nom?

Moreover, the performance of synthesized PAC was also very much higher as compared with aluminum sulfate and aluminum chloride for removing turbidity and NOM from synthetic water samples. The coagulant dose and the lime required of synthesized PAC were reduced more than two folds relative to aluminum sulfate and aluminum chloride doses.

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.
