以硅酸钠、硫酸镁和硫酸铝为原料，制备出聚硅酸硫酸铝镁（PAMSS）絮凝剂，将其用于对染料废水的脱色研究．结果表明，SiO2浓度为0.3mol/L ，硅酸活化pH＝3，活化时间30min ，n （Mg）∶ n（Si）＝1.25，n（Al）∶ n（Si）＝0.5时，其对活性染料脱色率可达到90％以上．实际废水处理结果表明，PAMSS处理印染废水具有良好的脱色效果，是一种高效的无机高分子絮凝剂．

The polysilicate magnesium sulfate (PAMSS) flocculant was prepared through sodium sili-cate ,magnesium sulfate and aluminum sulfate as raw materials and it was used for decolorization stud-ies .The results showed that the best condition was 0.3mol/L SiO2 concentration ,pH=3(silicic acid ac-tivated) ,30min activation time ,n(Mg)∶ n(Si)=1.25 ,n(Al)∶ n(Si)=0.5 .Its decolorization rate of re-active dye could reach over 90% .The experimental results indicated the decolorized effect of dyeing wastewater is good if PAMSS was used .PAMSS is a highly efficient inorganic polymer flocculant .
