Изобретение относитс к аналитической химии,1В частности к способам экстракционноН)отометрического определени талли .The invention relates to analytical chemistry, 1B in particular, to methods for the extraction of the isometric determination of thallium.
Цель изобретени - повьшение селективности .The purpose of the invention is to increase the selectivity.
Пример. К 25 мл раствора гидрооксида натри с концентрацией Ь,1 моль/л приливают .5 мл 8-хинолин- дитиокарбоксилата тетраэтиламмони b концентрацией 1-10 моль/л и раст- Ьор искусственной смеси, содержащий 81,75 мкг талли . Раствор перемеши- baraf и провод т экстракцию комплекса хлороформом в течение 3 мин. Экстракт фотометрируют при длине волны 310 нм. Найдено 83мкг,Т1. Относительна ошибка - мол рный коэффициент поглощени 840 1.5%. Example. To a 25 ml solution of sodium hydroxide with a concentration of b, 1 mol / l, is poured. 5 ml of tetraethylammonium 8-quinoline-dithiocarboxylate with a concentration of 1-10 mol / l and a solution of an artificial mixture containing 81.75 μg of thallium. The solution was stirred and the complex was extracted with chloroform for 3 minutes. Extract photometrically at a wavelength of 310 nm. Found 83mkg, T1. Relative error - molar absorption coefficient of 840 1.5%.
В таблице приведены сравнительные данные по селективности определени талли с использованием предлагаемого реагента и 3-индолдитиокарбокси- лата тетраэтиламмони (ТЭА). The table shows the comparative data on the selectivity of the determination of thallium using the proposed reagent and tetraethylammonium (3) indithiocarboxylate (TEA).
