摘　　要：以聚丙烯腈(PAN)为结构框架,制备了PAN/聚丙烯酸(PAAc)复合纤维膜,研究了其吸附动力学。结果表明:当N,N-二甲基甲酰胺、PAN、丙烯酸、丙烯酸羟丙酯、2-羟基-2-甲基-1-苯基-1-丙酮的质量分数分别为87.30%,9.70%,1.47%,1.47%,0.06%时,PAN/PAAc复合纤维膜对镍离子的吸附效率高达75.39%,且该吸附行为较符合准二级吸附动力学模型,其中,外扩散占主导作用。Using polyacrylonitrile(PAN)as the structural framework,PAN/polyacrylic acid(PAAc)composite fiber membrane was prepared and its adsorption kinetics were studied.The results show that when the mass fractions of N,N-dimethylformamide,PAN,acrylic acid,hydroxypropyl acrylate and 2-hydroxy-2-methyl-1-phenyl-1-acetone are 87.30%,9.70%,1.47%,1.47%and 0.06%,respectively,the adsorption efficiency of PAN/PAAc composite fiber membrane for nickel ions is as high as 75.39%.This adsorption behavior is in line with the quasi second order adsorption kinetic model with external diffusion playing a dominant role.
