Abstract

The sorption properties of acid-modified Transcarpathian clinoptilolite towards Sc(III) under dynamic conditions have been studied. It was found that the most effective acid-modifier is 0.5M HCl solution. Maximal sorption capacity is observed in the previously heat-treated at 50 °C samples of H-clinoptilolite in low alkaline solutions (pH=8.5). At this conditions almost all of the Sc(III) ions are in the form of neutral hydroxo complex [Sc(OH)3(H2O)3]. The sorption capacity of H-clinoptilolite towards Sc(III) ions under optimum conditions is 9.98 mg/g.

酸改性喀尔巴阡斜沸石对钪的吸附

研究了酸改性的喀尔巴阡斜沸石对Sc(III)的动态吸附性能。结果表明，0.5M HCl溶液是最有效的酸调节剂。在低碱性溶液(pH=8.5)中，先前在50°C下热处理的h -斜沸石样品观察到最大的吸附能力。在这种条件下，几乎所有的Sc(III)离子都以中性氢氧配合物[Sc(OH)3(H2O)3]的形式存在。在最佳条件下，h -斜沸石对Sc(III)离子的吸附量为9.98 mg/g。
