The reversed-phase extraction chromatographic separation of selenium(IV) and tellurium(IV) from several elements with trioctylphosphine oxide as extractant is reported. Selenium was extracted from 6M hydrochloric acid containing 7M lithium chloride was stripped with 4M hydrochloric acid, and tellurium was extracted from either the same medium as selenium or from 4M hydrochloric acid, and stripped with 1-2M hydrochloric acid. Selenium and tellurium can be separated from multicomponent mixtures.
报道了以三辛基氧化膦为萃取剂，从几种元素中反相萃取色谱分离硒（IV）和碲（IV）的方法。硒从含7M氯化锂的6M盐酸中萃取，用4M盐酸反萃取；碲从与硒相同的介质或4M盐酸中萃取，用1 - 2M盐酸反萃取。硒和碲能够从多组分混合物中分离出来。
