Abstract :
A new composite coagulant was prepared by polyaluminum chloride (PAC) and and polydimethyldiallylammonium chloride (PDMDAAC). The chemical species distribution, structure and surface charge of the composite coagulant (PAC-PDMDAAC) were studied by Al-Ferron complexation timed spectrophotometry, TEM and zeta potential measurement, respectively. And the coagulation efficiency of PAC-PDMDAAC was studied by comparing with that of PAC. The results show that there are some interaction between PAC and PDMDAAC. And the interaction is influenced by THE weight concentration of PDMDAAC (P%). Therefore, the coagulation efficiency of PAC-PDMDAAC is higher than that of PAC.
