| 摘 要： | 以硫酸铝、水玻璃和铝酸钠为原料合成出了具有不同碱化度(B)和si／Al摩尔比的聚合硅酸硫酸铝(PASS)混凝剂，用Al-Ferron逐时络合比色法和^27Al NMR法研究了PASS中铝的形态分布．结果表明，Si／Al摩尔比对PASS形态的影响要小于B值的影响；在一定的B值和Si/Al摩尔比下，Alb成为PASS中铝的优势形态；PASS中Alb和Ferron试剂的反应遵循准一级反应规律，其Kb差异不大．

| Abstract: | A series of polyaluminium silicate sulfate(PASS)with different basicities( B )and Si/Al molar ratios were prepared by using aluminum sulfate,water glass and sodium aluminum as raw materials.The species of PASS were studied by Al Ferron timed complex colorimetric method and 27 Al NMR spectroscopy method.The results show that the effect of Si/Al molar ratio on the species distribution of PASS is different from that of basicity;the Al Ferron complex colorimetric reaction of Al b in PASS solution follows the pseudo first order kinetics,and k b of different PASS does not very much. |
