The cellulose was extracted from peanut hull(CEPH) by Milox method,then super absorbent polymer(SAP) was prepared from the cellulose by inverse emulsion polymerization with N,N’-methylenebisacrylamide as crosslinker and potassium persulfate as initiator.The effects of monomer proportion,neutral degree of acrylic acid(AA),amounts of the initiator and crosslinker on the water absorption rate were discussed through orthogonal test.The results show that when the monomer composition(m(AA)∶m(CEPH)) is 8∶1,neutral...
