【摘要】 首次报道了用双乙烯酮与氨基聚苯乙烯缩合制得N-乙酰乙酰苯胺基螯合树脂的方法。试验树脂对十几种金属离子的螯合性能,结果表明,pH=4.0时树脂对Be²⁺有良好的吸附选择性,其吸附容量为0.43m mol/g干树脂。用6mol/L H₂SO₄可从树脂柱上定量洗脱出Be²⁺。更多还原

【Abstract】 A method for the preparation of chelating resin containing acetoacetanilide group was reported based on the condensation reaction of diketo with aminopolystyrene in toluene at atmospheric temperature, The resin is stable in fairly strong acid or alkaline solution. The sorption patterns of several metal ions have been studied at varying pH. The results showed that the resin has a good selectivity to Be⁽（2+） at pH 4.0. The adsorption capacity was 0.43m mol/g-resin. The Be²⁺sorbed on the resin column can be quan- titatively eluted with 6mol/L H₂SO₄,更多还原
