本文研究了用5%三异辛胺的四氯化碳溶液从盐酸和溴氢酸中萃取Pd(Ⅱ),Rh(Ⅲ),Ir(Ⅲ),Au(Ⅲ)和Pt(Ⅳ).金自盐酸中的萃取物为黄色,在325nm有吸收.钯化合物是红色的,在290nm 和467nm有吸收.铂化合物是血红色的,在268nm有吸收.AU、Pd、Pt 自溴氢酸中的萃取物为绯红色、红棕色和血红色,最大吸收分别为260、345和300nm.方法用于自铂中分离金和进行金的测定,也可用于同时测定铂和钯.
In this paper, the extraction of Pd (Ⅱ), Rh (Ⅲ), Ir (Ⅲ), Au (Ⅲ) and Pt (Ⅳ) from hydrochloric acid and hydrobromic acid with 5% triisooctylamine in carbon tetrachloride The extract from hydrochloric acid is yellow and has absorption at 325 nm. The palladium compound is red and has absorption at 290 nm and 467 nm. The platinum compound is reddish and has absorption at 268 nm. AU, Pd, Pt Extracts were crimson, reddish brown and reddish red with maximum absorptions of 260, 345 and 300 nm, respectively.The method was used for the determination of gold and gold from platinum and also for the simultaneous determination of platinum and palladium.
