摘要
通过吸附历时过程、饱和吸附量、吸附过程Na^+离子交换释放、絮凝前后高岭土微粒的电位测定等实验考察AICI_3(AC)和聚合铝(PAC)两种不同形态的铝盐对高岭土悬浮水样的吸附电中和特征,并探讨了其作用机理。
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
