Изобретение относитс  к способам кощентрировани  рени  путем экстрации преимущественно дл  его последующего фотометрического определени оThe invention relates to methods for the centrification of rhenium by extraction mainly for its subsequent photometric determination of

Известны способы экстракционкого извлечени  рени  в виде комплексного соединени  с органическими и неорганическими реагентами дл  последующего определени  рени  фотометрическим методом. Дл  образовани  комплексного соединени  ввод т, например, трехвалентное железо, роданид кали  и экстракцию провод т органическим растворителем .Methods are known for the extraction extraction of rhenium as a complex compound with organic and inorganic reagents for the subsequent determination of rhenium by the photometric method. For the formation of the complex compound, for example, trivalent iron, potassium rodanide and the extraction are carried out with an organic solvent.

Однако при использовании известного способа извлечени  дл  аналитического определени  рени  одновременно с рением извлекаютс  и другие элементы, образующие аналогичные роданидные кокшлексы, например медь, молибден, вольфрам.However, when using a known extraction method for analytical determination of rhenium, other elements are also extracted simultaneously with rhenium, forming similar rhodanide coxlexes, for example, copper, molybdenum, and tungsten.

С целью повышени  избирательности процесса предложено в качестве реагента вводить ферроин и экстракцию проводить нитробензолом. При этом ферроин ввод т при рН 2-9.In order to increase the selectivity of the process, it was proposed to introduce ferroin as a reagent and conduct extraction with nitrobenzene. Ferroin is then introduced at a pH of 2-9.

A sample of sample 0, L2.0 .0 g is decomposed in nitric acid (1: 2), evaporated in a water bath to wet salts, 10 ml of concentrated hydrochloric acid is added and evaporation is continued. The wet salts are dissolved in 25 ml of water, about 100 mg of the dry salt of Trilon B is added, neutralized with an alkali on Congo paper to a pH of 4-5, the solution is transferred into a 100 ml volumetric flask with water. An aliquot of 10 ml of the resulting solution was placed in a 100 ml separatory funnel, delivered with 2 ml of universal buffer pH B – 6, 2 ml of a 0.005 M solution of ferroin and water to a total volume of 15 ml. 10 ml of nitrobenzene are poured in and shaken for 1 minute.
