Platinum(IV) was extracted from chloride solution using kerosene solution of trioctyl ammonium chloride, methyltrioctylammonium chloride, and tetraoctyl ammonium chloride ionic liquids as solvents in high yields. To increase the Pt(IV) recovery and heterogenize the process for easy handling at industrial scale, these three ionic liquids were directly impregnated on some solid carriers, such as silica gel-60, silica gel-100, Amberlite XAD-7 ion-exchange resin, and Amberlite XAD-7 ion-exchange resin to form sorbents in nature of supported ionic liquid phase. The influence of some factors, such as ionic liquid and solid carrier structure, IL/Pt molar ratio, and ionic liquid loading as well as sorption isotherms, was investigated. The stripping and desorption of Pt(IV) using different eluents and reusability of ionic liquids and supported ionic liquid phases were also evaluated.

使用浸渍铵离子液体的固体载体从氯化物溶液中回收铂 (IV)

使用三辛基氯化铵、甲基三辛基氯化铵和四辛基氯化铵离子液体的煤油溶液作为溶剂以高收率从氯化物溶液中提取铂(IV)。为了提高 Pt(IV) 回收率并使工艺多相化以便于工业规模处理，这三种离子液体直接浸渍在一些固体载体上，如硅胶-60、硅胶-100、Amberlite XAD-7 离子交换树脂和 Amberlite XAD-7 离子交换树脂形成负载离子液相性质的吸附剂。研究了一些因素的影响，如离子液体和固体载体结构、IL/Pt 摩尔比、离子液体负载以及吸附等温线。
