摘要
在细乳液体系中采用原子转移自由聚合(ATRP)制备聚丙烯腈(PAN)微球,然后用盐酸羟胺对其进行肟氨化改性,并将其用于Zn^(2+)的吸附研究.通过傅立叶变换红外光谱,扫描电镜(SEM)分析了肟氨化聚丙烯腈微球的结构.用原子吸收光谱测定了聚丙烯腈微球的吸附性能.结果表明,交联剂的用量以及溶液的pH值对Zn^(2+)的吸附量均有影响.在本研究的条件下Zn^(2+)的吸附量可达到0. 0421 mmol/g.
Polyacrylonitrile(PAN) microspheres were prepared by ATRP in miniemulsion system. The PAN was modified with hydroxylamine fiydrochloride and then was applied in the adsorption of Zn^2+. The structure of the amidoxime PAN was analyzed by FT-IR and SEM. The adsorption properties of the amidoxime PAN microspheres were determined by atomic adsorption spectroscopy. The results showed that the amount of crosslinking agent and pH affects the adsorption amount of Zn^2+,which,in this study,is 0. 0421 mmol/g.
