Zeta Potential of Stable Oxidative Poly-Si-Fe (SOPSF) Coagulant

Ying Fu, Nan Shi, Hong Lan Li

Abstract

Characteristics of Zeta potential of a stable oxidative poly-Si-Fe (SOPSF) coagulant was studied with Nano Zetasizer, in comparison with that of polyferric aluminum (PFA). The results showed that the reaction between polysilicic acid (PS) negative charged and Fe positive charged is complicated, instead of a simple electro neutrality process. The Zeta potentials of SOPSF are almost near to the isoelectric point at higher concentration, while the Zeta potential of PFA is about 20 times that of SOPSF carrying negative charges at the same concentration. But after dilution, the Zeta potential of SOPSF is about equivalent to that of PFA.
