Graft copolymerization of itaconic acid onto ramie fibers was studied with ammonium persulfate as initrictor. The effect of parameters such as concerntrations of ammonium persulfate, itaconic acid and H + as well as temperature and reaction time of polymerization on the graft yield is examined. The optimum condition for grafting is ammonium persulfate 3×10 -2 mol·L -1 , itaconic acid 1.80 mol·L -1 , H + 1.0 mol·L -1 , temperature 50 ℃ and time 72 h.In this paper, the adsorption behaviors of the grafted ramie fibers towards metal ions have been investigated. 过硫酸铵 苎麻纤维 衣康酸 接枝共聚合 离子吸附 ammonium persulfate ramie fibers itaconic acid craft copolymerization metal ions adsorption Q5-33 1999-06-01 2021-04-01 6
