【摘要】 利用活化硅酸和硫酸铁为原料,在不同碱化度和Si/Fe摩尔比条件下,制备出聚合硅酸硫酸铁(PFSS)无机高分子絮凝剂。考察影响产品稳定性的因素,并分析了产品Fe(Ⅲ),Si(Ⅳ)的形态分布特征,对其可能原因做出微观解释。更多还原

【Abstract】 The polymetric ferric silicate sulfate, (PFSS) prepared with ferric sulfate and PS, is studied at different OH/Fe molar ratio and Si/Fe molar ratio. The product stability was discussed; Fe(III) and Si(IV) species distribution characteristics were analyzed and their possible causes of such distribrbion are explained microscopically.更多还原
