中文摘要: 研究了不对称亚砜(BSO)萃取钯、铂的行为及机理。结果表明:酸度对钯、铂的萃取率和萃取机理有很大影响。在低酸度时,BSO萃取钯主要是中性配位萃取机理,对钯的萃取率接近100%,而对铂的萃取率极低;在高酸度时,BSO萃取钯、铂的机理都是离子缔合萃取,且对钯、铂的萃取率均已接近100%。利用BSO在低酸度下萃取钯、铂可以实现钯、铂的有效分离。氨水为钯的高效反萃剂,蒸馏水为铂的高效、经济反萃剂。

Abstract:The extraction behavior and mechanism of palladium and platinum with unsymmetrical sulfoxide (BSO) were studied. The results show that acid concentration works on the extraction mechanism and extraction rate of palladium and platinum. At a low aqueous acidity, BSO acts as a neutral ligand coordinated with palladium, and the extraction rate of palladium achieves 100%. At a high aqueous acidity, the extracting mechanism of palladium and platinum are acid ion association extraction, and the extraction rate of palladium and platinum achieves 100%. Palladium and platinum can be separated effectively at a low aqueous acidity with BSO. Ammonium solution is a high efficient stripping agent to palladium and water is a high efficient stripping agent to platinum.
