and complexation properties towards a set of metal ions (FeIII, AlIII, and ThIV) were studied by potentiometry and spectrophotometry. The ligand was further immobilized in an epoxy-activated sepharose by chemical coupling through the aminoalkyl pendent group with the aim of improving its sequestering capacity for residual amounts of metals. The new hydroxypyrimidinone-functionalized sepharose shows
合成了1-羟基-2-(1H)-嘧啶酮衍生物4-(3-氨基丙基氨基)-1-羟基-2-(1H)-嘧啶酮(HOPY-PrN),并对其酸碱和络合性质进行了研究通过电位测定法和分光光度法研究了金属离子(FeIII、AlIII 和 ThIV)的浓度。配体通过氨基烷基侧基化学偶联进一步固定在环氧活化的琼脂糖凝胶中,目的是提高其对残留金属量的螯合能力。新的羟基嘧啶酮功能化琼脂糖凝胶在 pH 3-8 范围内对金属离子显示出高螯合能力,因此为潜在的环境应用提供了良好的前景。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
