| Abstract: | A kind of novel amino fiber was prepared from styrene grafted polypropylene(PP-g-St) fiber through acetylation and amination reaction.Factors affecting the acetylation process,such as reaction time,temperature,catalyst and the amount of acetyl chloride,were investigated.The effects of mol-ratio of amine vs.acetyl,amine vs.paraformaldehyde and amine vs.hydrochloric plus reaction time were also studied to obtain the optimum amination conditions by orthogonal experiment design.The results show that the adsorption capacity of Cu2+ could reach 2.00mmol/g by this kind of amino fiber. |
