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 27Al 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 Alb in PASS solution follows the pseudo first order kinetics,and kb of different PASS does not very much.
