| Abstract: | In A1C13 and polyaluminum solutions,Al (III) has different species. To investigate their different mechanism of flocculation,adsorption and coagulation experiments with kaolinite suspension were carried out. The maximum adsorption amount,Na+ released amount during ion-exchanging adsorption and the change of elec-trophoretic mobilities (potentials) were carefully measured. On the basis of experimental results,the adsorption characteristics of aluminum salts on kaolinite and the coagulation mechanism of kaolinite suspension by two coagulants were presented. Compared to Al (III),the polycation in PAC solution were found to be more effective in charge neutralization and turbidity removal |
