摘要
Ｎ＿（１９２３）萃淋树脂是胺类萃淋树脂。本文报道了该树脂在酸性体系中对钯的静态分配比。讨论了温度、树脂用量，振摇时间对吸附钯的影响。确定了吸萃物的组成比，并用红外光谱探讨了树脂吸附钯的机理。在此基础上，进行树脂的柱色层试验，结果表明此树脂为萃取色层的新固定相，树脂上吸附的钯可用０．０５０ｍｏｌ／Ｌ硫脲－０．５０ｍｏｌ／ＬＨＣｌ溶液解脱，树脂可再生和重复使用。
This paper studied the adsorption proper-ties and distribution ratio of N_(1923), levextrelresin. The composition of palladium com-pounds extracted by prime amine N_(1923) levex-trel resin in acidic solution was determined bydifferent methods.he composition is The mechanism of adsorp-tion of this resin was also analysed by IR spec-tra. The resuIts of column operation show thatN_(1923) levextrel resin is a novel material for ex-traction chromatography of inorganic salts. Pd(Ⅱ)adsorbed on the resin can be eluted quan-titatively by a solution of(NH_2)2CS. The resincan be regeherated and reused.
