Particle size effect of nano poly aluminum silicate chloride:Coagulation characteristics and the interaction between Al13 and activated sodium silicate
纳米复合聚硅酸铝的颗粒粒度效应:Al13与氧化硅的相互作用及其混凝特征

To study the effect of particle size of nano poly aluminum silicate chloride (PASC),a series of composite PASC with different particle size distributions were prepared from Al13 and activated sodium silicate. Aluminum species detected with Al-Ferron reaction kinetics showed that Al13,the predominant form in PASC,has good stability. The polymerization degree and particle size analysis of activated sodium silicate indicated that adding silicate could significantly increase the average particle size of the coa...
