摘要: Graft copolymerization of acrylonitrile onto maize starch by a simultaneous irradiation technique using gamma-rays as the initiator was studied with regard to various parameters importance: monomer-to-maize ratio and total dose (kGy). The water absorption modified measured. gives low absorbance. Conversion copolymer amidoxime form high swelling. gel (%) grafting efficiency were An investigation carried out study adsorption basic violet 7, blue 3, direct yellow 50 acid red 37 from aqueous solutions water-insoluble containing groups rice straw. effects initial pH solution, pollutant concentration treatment time on it found that maximum at 1:2 (starch/acrylonitrile) 30 kGy.
