摘　　要：采用复合法制备了具有不同碱化度、不同铝硅摩尔比的一系列聚合硅酸硫酸铝(PASS),并对不同pH值的印染废水进行了处理。用Al-Ferron逐时络合比色法研究了PASS的形态分布,分析了各因素对PASS形态分布的影响,最终得出了聚铝硅絮凝剂的最佳制备条件。A series of polyaluminum silicate sulfate （PASS） with the different basicity and AI/Si molar ratios were produced by the composite polymerization （COMPOLY） techniques, and used to treat the printing wastewater of different pH. The species distribu- tion of PASS was made by AI Ferron timed complex colorimetric method. The influence of various factors on the species distribution was analyzed in this paper. Finally, the optimum prepared condition of PASS is obtained.
