| 摘 要： | 通过调控SiO2含量、Zn/Si物质的量比、聚合时间、pH值等制备了新型絮凝剂聚硅酸硫酸锌(PZSS),采用红外光谱法研究了上述因素对PZSS结构的影响。结果表明,PZSS的聚合形态结构取决于SiO2含量、Zn/Si物质的量比、聚合时间、pH值等的大小。红外光谱证实了PZSS中Zn2 及水解Zn2 离子可与共存的聚硅酸起螯合反应生成锌硅聚合物,聚硅酸与Zn2 反应并不是单纯的物理混合加成作用,而是形成了具有特殊结构的无机高分子的化学反应,这种新型絮凝剂所具有的优良絮凝特性是由各物质间以化学作用为主的物理化学因素共同作用的结果。 |

| Abstract: | A new type of flocculant-polyzinc silicate sulfate(PZSS) with different concentrations of SiO2,Zn/Si molar ratios,polymerization times and pH values were prepared and the effects of such preparation parameters on the structure were studied with IR spectroscopy.The results showed that the structure of PZSS was dependent on the concentration of SiO2,molar ratio of Zn/Si,polymerization time,pH value and so on.It was proved by IR spectroscopy that Zn2 and hydrolyzed ion were chelated with polysilicic acid to produce the polymer of zinc-silicon.The reaction was not the simple physical blending,but the chemical reaction forming the inorganic polymer with special structure.The better flocculating efficiency was resulted mainly from the chemical and physico-chemical factors among the components. |
