Abstract
Abstract Functional monomer [N-(2,4,4-trimethylpentan-2-yl)acrylamide] was synthesized and characterized by MS and NMR. A series of high molecular weight cationic polyacrylamides were prepared with N-(2,4,4-trimethylpentan-2-yl)acrylamide, acrylamide and methacryloxyethyltrimethyl ammonium chloride by copolymerization using complex initiation systems as catalysts in aqueous solution. Then they used as flocculants to treat the paper-making wastewater. The removal of the colour and the chemical oxygen demand (COD) in the treated waste water samples were determined. Results showed that flocculants could efficiently remove the color and the COD. The overall color and COD removal efficiencies reached as high as 80% and 85%, respectively.
