摘要: 合成了八种氨基(β羟基)甲酸酯树脂与氨基(β-羟基)亚磺酸酯树脂。探讨了溶剂、试剂摩尔比、反应温度与时间对制得的树脂功能基含量、吸附容量的影响.在一定的pH及酸度范围内,在杂质离子Ni2+、Cu2+、Zn2+、Mn2+、Cd2+存在下,树脂5高选择性地定量吸附Au(Ⅲ);树脂对Au(Ⅲ)、Pt(Ⅳ)、Pd(Ⅱ)有选择吸附性。

Abstract: Eight kinds of resins bearing amino (β-hydroxyl ) formate groups or amino (β-hydroxyl ) sulfitc groups were synthesized.The influence of solvents,mole ratio of reagents,reaction temperature and reaction time on tiic contents of functional group and the adsorption capacity of Au(Ⅲ) were discussed.The effects of pHand acidity on the adsorption of Au(Ⅲ),Pt(Ⅳ) Pd(Ⅱ) were examined.Au(Ⅲ) can be absorbed by resin5 in the presence of Ni2+,Cu2+,Zn2+,Mn2+ Cd2+ with high selectivity.
