中文摘要: 研究了MCI-GEL树脂分离富集钯的行为及与一些金属离子分离的条件。结果表明,钯与N,N-二羟乙基甘氨酸(Bicine)形成的配合物能被MCI-GEL树脂吸附。当溶液中N,N-二羟乙基甘氨酸与钯的摩尔比为2∶1、盐酸浓度0.01 mol/L、过柱流速10 mL/min时,Pd(Ⅱ)可与Pt(Ⅳ)、Fe(Ⅲ)、Ni(Ⅱ)、Cu(Ⅱ)、Zn(Ⅱ)定量分离,且钯的萃取率达99%以上。

Abstract:The behavior of and conditions for separation and enrichment of palladium from metal-ions by MCI-GEL resin were studied. The results show that the complex compound formed by palladium and Bicine can be adsorbed by MCI-GEL resin. Palladium could be quantitatively separated from Pt(Ⅳ), Fe(Ⅲ), Ni(Ⅱ), Cu(Ⅱ), Zn(Ⅱ) by extraction with palladium extraction rate of above 99% under the conditions including molar ratio of Bicine and palladium of 2∶1, hydrochloric acid concentrations of 0.01 mol/L and column flow rate of 10 mL/min.
