Abstract

A cationic polymeric flocculant was synthesized through solution polymerization. The polymerization was initiated by acrylamide and Aacryloxyethyltrimethyl Ammonium Chloride(DAC) monomers, and ammonium persulfate and sodium sulfite as redox initiation system. The copolymer obtained was characterized by Fourier-transform infrared (FTIR) spectroscopy. Its flocculating properties were evaluated by turbidity removal with clay suspensions, turbidity and COD removal with sewage using standard jar tests. The results demonstrate that the copolymer can be used as a kind of cationic polymeric flocculant in water and wastewater treatment.
