N-正辛基苯胺的二甲苯溶液用于从酸性介质中萃取分离铂。铂（IV）分别用10 ml 3%试剂的二甲苯溶液从0.5 - 10 M盐酸和2.5 - 10 M硫酸中定量萃取。用水将其从有机相中反萃取，并用氯化亚锡进行光度测定。研究了金属离子、酸、试剂浓度和各种杂质离子对测定的影响。该方法提供铂（IV）与铁（III）、钴（II）、镍（II）和铜（II）的二元分离，并且适用于合成混合物和合金的分析。方法快速、准确、精密。
N-n-octylaniline in xylene is used for the extractive separation of platinum(IV) from acidic media. Platinum(IV) was extracted quantitatively with 10 ml of 3% reagent in xylene from 0.5 to 10 and 2.5 to 10 M hydrochloric and sulphuric acid, respectively. It was stripped from organic phase with water and estimated photometrically with stannous chloride. The effect of metal ion, acids, reagent concentration and of various foreign ions has been investigated. The method affords binary separation of platinum(IV) from iron(III), cobalt(II), nickel(II) and copper(II), and is applicable to the analysis of synthetic mixtures and alloys. The method is fast, accurate and precise.
