【摘要】 以Ce⁴⁺引发丙烯腈与罗布麻纤维接枝共聚反应,用红外光谱表征了接枝纤维的结构。并探讨了接枝纤维皂化物时汞离子的吸附性能。C_AN为1.2×10^-1mol/L、C_Ce⁴⁺为10×10^-3mol/L时接枝率较高,该接枝共聚物经皂化后能有效地吸附汞离子,pH值在10～11时吸附率最高,达0.583mg Hg²⁺/g。更多还原

【Abstract】 In this paper, the graft copolymerization of acrylonitrile (AN) onto apocynum were carried out using Ce4+ as initiation system. The structure of graft fiber were characterized by IR spectra, the adsorptive function of saponated grafted-fiber to Hg ion was studied. WhenCAN is 1. 2×10-3 mol/L, CCe4+ is 10×10-3 mol/L,the higher grafting is abtained. . The saponated grafted-fiber has the function to adsorb Hg ion, the adsorption rate is 0. 583 μg Hg2+/mg saponated grafted-fiber . When pH is 10-11, the adsorption rate is the highest..更多还原
