Abstract


Here, cationic polymer was synthesized by radical polymerization. The influences of temperature, polymerization time on the cationic polymer were investigated. The results show that polymerization temperature, molar ratio of reactant, polymerization time all have a great effect on the cationicity and the viscosity of the polymer. The structure of the polymer and its aggregation in aqueous solution were examined by means of various instrumental analysis techniques including FTIR, ~1HNMR. The coagulation efficiency and decoloration efficiency of the polymers for dyeing wastewater and oil refinery effluent were studied. The experimental results show that the cationicity and the viscosity have a great effect on the coagulation efficiency and decoloration efficiency of polymer. Thus the cationicity and viscosity should be geared to difference wastewater. Generally, for dispersed dyeing wastewater, cationic polymer perform mainly as adsorption bridging agents, while for water-soluble dye wastewater, cationic polymer show both charge neutrallization and adsorption bridging functions. In conclusion, a certain kind of wastewater needs the cationic with special structure. The cationic polymer was functionalized in the wastewater by charge neutralization and adsorption bridging mechanism. The experimental results showed that the cationic polymer was organic flocculant with high performance and multi-function. The cationic polymer is also environment friendly.The bentonite was modified with the cationic polymer as intercalary reagent by cationic polymer direct intercalation method. The structure of the bentonite and cationic/bentonite were examined by means of various instrumental analysis techniques including FTIR, SEM. The influences of polymer concentration and different experimental conditions on the formation of cationic/bentonite were investigated. The results indicated that the adsorption capacity of cationic/bentonite was better than that of raw bentonite obviously.
