- How to manufacture polyaluminium chloride?
- Method for manufacturing polyaluminium chloride with aluminum vanadine and calcium aluminate powder CN104671269A(en) 2015-06-03 Method for producing polyaluminum chloride from hydrogen chloride waste gas and aluminum salt water waste liquid generated from anthraquinone synthesizing production
- 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 preformed polyaluminum salt?
- Polyaluminum chloride (PAC) is a preformed polyaluminum salt that can be produced by adding base to aluminum chloride until an empirical formula of Al (OH)nCl3-n (with n from 1.0 to 2.5) is achieved. A variety of species can be formed when stock solutions of PAC are added to a raw water.
