| Abstract: | Polyaluminum chloride are prepared from aluminum ash by acid dissolution, parameters that influence the performance of PAC, such as reaction, temperature, reaction time, aging temperature, aging time, the ratio of aluminum ash, HCI and water, are investigated. The optimum conditions for the preparation of PAC are determined, namely the initial waterl5ml, ratio of water and acid is 1, dosing quantity is 3 g, react 2 h in 85℃, aging 48 h in 50℃ The precent of chloride is increased to 12%-14% from the past 6%-8%. |
