摘　　要：制备了一种新型的改性增效聚合铝类多核无机高分子絮凝剂聚合氯化铝锌(PAZC)。通过Al-Ferron逐时络合比色法,对PAZC溶液的形态分布进行了考察,研究了不同碱化度(B)和不同Al/Zn摩尔比和陈化时间对PAZC形态分布的影响。结果表明,将Zn引入PAC并非是简单的混合,而是发生了一定的相互作用,表现在PAZC中铝形态分布取决于Al/Zn摩尔比、碱化度B及陈化时间等因素。A new muhicore inorganic polyaluminum composite flocculant named polymeric aluminum zinc chloride （PAZC） was prepared. Effects of basicity,Al/Zn molar ratio and aging time on aluminum speciation were studied by ferron - complexation timed spectropyotometry. Results showed that PAZC was not a simple mixture of raw materials but a complexation formed by polymerizing Al and Zn and its aluminum speciation depended on such factors as basicity .Al/Zn molar ratio and aging time.
