Synthesis and Adsorption Properties of Crosslinked Starch Microspheres (CSM)

Abstract:

Starch as the material, MBAA as the cross-linking agent, Tween60 and Span60 as the emulsifier, K₂S₂O₈-Na₂SO₄ as the initiator, the cyclohexane as the oil phase and the removal rate of methyl violet as an index, crosslinked starch microspheres (CSM) was synthetized by means of reverse suspension emulsion and graft-copolymerization method through orthogonal test and single factor optimization experiment. The results showed the optimal conditions of the preparation of the crosslinked starch microspheres(CSM) were as follow: the concentration of the starch is 5%, the dosage of the MBAA, initiator and emulsifier are 0.125g, 0.5g and 0.6g, the volume ratios between the Span60 and Tween60 is 85:15, and the volume ratio between the cyclohexane and water is 4:1.
