Study on the Flocculating Performance of Modified Starches

Abstract:

pea starch and acrylamide were used as the raw materials, potassium peroxodisulfate and sodium sulfite were used as the initiator, EDTA (Ethylene Diamine Tetraacetic Acid) and urea were used as the auxiliaries to make starch grafting acrylamide polymer flocculating agent by the method of aqueous solution polymerization. The influence of reaction temperature, concentration of initiator and raw material ratio on the flocculating performance of products was analyzed by ternary quadratic orthogonal regression rotational combination experiment. The result shows that the flocculation effect will be the best when the reaction temperature is 60°C, the initiator is 5.00 ml, and the raw material ratio is 2.25.
