巯基苯二胺型螯合树脂的合成及其吸附性能（ⅩⅩⅧ） SYNTHESIS AND ADSORPTION PROPERTIES OF THIOLPHENYLENE DIAMINE TYPE CHELATING RESINS 徐羽梧 1 first-author 李汉平 1 董世华 1 武汉大学化学系 武汉大学化学系 Department of Chemistry,Wuhan University Department of Chemistry,Wuhan University 用环硫氯丙烷分别与ｏ、ｍ、Ｐ－苯二胺进行开环、缩聚反应，合成了一类新的巯基苯二胺型资合树脂．３种苯二胺异构体的反应活性顺序为：ｐ－＞ｍ－＞ｏ－．研究了这类树脂对贵金属的吸附性能，其中以含ｐ－苯二胺结构的树脂性能较好．它对ＡＵ（Ⅲ）和Ａｇ（Ⅰ）具有高的吸附容量；对Ｐｄ（Ⅱ）有一定的吸附；但对Ｐｔ（Ⅳ）则几乎不吸附． Three new thiol-phenylene diamine type chelating resins were synthesized byreaction of o,m,p-phenylene diamine with chloromethylthiirane respectively. The order of reaction activity of three isomers. was p->m->o-. Among three analogies,resin containing pphenylene diamine structure was the best one which had high adsorption capacity for goldand silver（～7. 3 mmol. g-1）,and rather low for palladium,but adsorbed platinum hardly. 螫合树脂 苯二胺 环硫氯丙烷 贵金属 吸附 O633.21 国家自然科学基金(61672102) 1995-04-01 2021-04-01 4
