In order to study the correlation between inorganic polymer and organic polymer in dual polymer coagulant, the hydrolysate properties of a new dual polymer coagulant, which was composed of polyferric chloride (PFC) and polydimethyldiallylammonium chloride (PDMDAAC), were investigated by examining Fe(III) speciation and zeta potential. Experiments were conducted to analyze the impact of weight concentration of PDMDAAC (Wp), basicity (B) of PFC and intrinsic viscosity (η) of PDMDAAC on the properties of the hydrolysis product of PFC-PDMDAAC The Fe-Ferron method was used to examine Fe(III) speciation. The results show that the content of Fe(III) momoneric species of PFC-PDMDAAC is lower than that of PFC, and the content of Fe(III) polymer and colloids species of PFC-PDMDAAC is higher than that of PFC. Malvern Zetasizer 3000 was used to measure Zeta potential. PFC-PDMDAAC has a significantly higher positive charge compared to PFC. The zeta potential of PFC-PDMDAAC is higher than 20mV when pH is from 4.0 to 8.0.
