Research on the Effect of Synthesis of Al-based Coagulants by Pulse Auto-rearrange able Electrodes Electrolysis through AddingPoly SiO_3^(2-) and SiO_3^(2-) Ions

探索了实验过程中聚合S iO32-和SO42-离子团的加入对脉冲自动倒极电解合成聚合氯化硅酸硫酸铝、聚合氯化硅酸铝、聚合氯化硫酸铝和聚合氯化铝产品稳定性的影响,确定了最佳的合成条件.然后采用酸解、碱聚和陈化镜检,对产品的稳定性进行了研究.结果表明:聚合S iO32-与SO42-离子对聚合铝凝剂稳定性的影响大小顺序为:S iO32-+SO42->SO42->S iO32-.

The impact of poly SiO3^2- and SO4^2- ions on the stability of Al-based coagulants produced by Pulse Auto-rearrange able Electrodes Electrolysis was investigated in this paper. Al-based coagulants includes poly-aluminum silicate sulfate chloride （PASSC）, poly-aluminum silicate chloride （PASiC）, poly-alumihum sulfate chloride （PASC） and poly-aluminum chloride （PAC）. Their stability was studied by acid addition, base addition and long time aging , which shows that the impact of poly SiO3^2- and SO4^2- ions on the stability of Al-based coagulants is poly SiO3^2- and SO4^2- 〉SO4^2- 〉poly SiO3^2-.
