高位阻叔胺(N_(3418))自盐酸溶液中萃取铂的研究

Study on the Extraction of Platinum With High Sterically Hindered Tertiary Amine(N_(3418))From Hydrochloric and Medium

本工作以高位阻叔胺萃取剂N34 18自盐酸溶液中对铂 (Ⅳ )的萃取进行了研究。对萃取时间、水相的酸度、水相的 pH值、萃取剂的浓度、稀释剂等影响因素进行了较全面的分析。用NaOH作为反萃剂对反萃率进行了研究。应用连续变换法、饱和法 ,斜率法确定了萃合物的组成 ,萃合物的组成为 1 4。

The extraction method of Platinum(Ⅳ)with high sterically hindered tertiary amine from hydrochloric acid medium is studied in this paper.The influence factors,such as extraction time,acidity and pH value of aqueous phase,the concentration of extracting agent and inert solvent are discussed.The stripping rate is studied using sodium hydroxide as stripping agent.In addition,the composition of the extracted complex is 14 confirmed by continuous varying method,the saturation method and the slope coefficient method.
