摘　　要：本文研究了以Fe^(2+)—H_2O_2为引发体系,丙稀腈与亚麻纤维的接枝共聚反应,并探讨了接枝亚麻皂化物作为离子吸附纤维对汞离子的吸附率。[Fe^(2+)]为4×10^(-3)mol/L、[H_2O_2]为4×10^(-3)mol/L、[H^+]为6×10^(-2)mol/L,在40℃反应2小时,可以得到较高接枝率。皂化后的亚麻纤维50毫克以上在适宜的pH值条件下。The graft copolymerization of acrylonitrile(AN)onto flax fiber were carried out using Fe2+-H2O2 as initiation system, the optimum grafting condition were found from our studies, in which the concen tration of [Fe2+].[H2O2],[H+],[AN], reaction temperature and time were varied and fixed concentration of all other. The maxmum grafting percentage(G%)was abtained at [Fe2+] of 4×10-3 mol·/L, [H+] of 6×10-2mol/L, [H2O2] of 4×10-3 mol/L at 40℃ 2hrs. The adsorbtive power of saponated grafted-fiber to Hg ion was preli minary studied in this thesis, with the fiber amount increase, the adsorbtive power increase, In suitable pH condition 50 mg of the fiber can adsorbed 85% of Hg ion in the same solution.
