Abstract

No primary scandium (Sc) ore exists on the earth and therefore securing a stable supply of Sc is required. The authors reported previously that a hexane solution containing 0.1 mol dm-3 of O,O-bis(2-ethylhexyl) hydrogen thiophosphate (MSP-8®) could extract Sc(III) quantitatively from an aqueous solution containing 1.0 mol dm-3 of zirconyl (ZrO(II)) and 0.10 mol dm-3 of tripotassium citrate as a masking reagent. The present study was carried out in order to establish the liquid-liquid extraction separation of Sc from a simulated waste water produced in the zirconium (Zr) refinery by using MSP-8 as the extractant.

O,O -二(2-乙基己基)硫代磷酸氢萃取分离废水模拟溶液中的钪(III

地球上不存在原生钪(Sc)矿石，因此需要确保稳定的Sc供应。作者先前报道了含有0.1 mol dm-3的O,O-二(2-乙基己基)硫代磷酸氢(MSP-8®)的己烷溶液可以从含有1.0 mol dm-3的锆基(ZrO(II))和0.10 mol dm-3的柠檬酸三钾作为掩蔽剂的水溶液中定量提取Sc(III)。以MSP-8为萃取剂，建立了从锆精炼厂模拟废水中萃取钪的液液分离方法。

期刊介绍： Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
