Preparation of Cationic Polyacrylamide Flocculant and its Application in the Treatment of Coal Slurry Wastewater

Abstract:

A cationic polyacrylamide flocculant (CPAM) for the coal slurry wastewater, was firstly synthesized using acrylamide and cationic monomer ethylene methyl propenoyl trimethylammonium chloride (DMC). The structure of the synthesized CPAM was characterized by means of FT-IR measurement, and the effects of various factors on flocculation performance were studied. The optimum flocculation can be achieved according to the dosage of flocculant between 2 and 5 mg/L, pH value of 6, temperature of 40°C, and the dosage of DMC in CPAM of 17.5%.
