Изобретение относитс  к области аналимческой химии, в частности к способам определени  полисернистых соединений.This invention relates to the field of analytical chemistry, in particular, to methods for determining poly-sulphurous compounds.

Известен способ фотометрического определени  полисернистых соединений с обработкой анализируемого раствора цианистым калием . В результате взаимодействи  пюлисернистого соединени  с цианистым калием образуютс  роданид-ионы, которые регистрируютс  фотометрическим методом.The known method of photometric determination of poly-sulphurous compounds with the treatment of the analyzed solution with potassium cyanide. As a result of the interaction of a pulpyl compound with potassium cyanide, rodanide ions are formed, which are detected by the photometric method.

С целью повышени  точности и чувствительности анализа предлагаетс  в качестве цианистого реагента использовать феррициа«ид кали .In order to increase the accuracy and sensitivity of the assay, it is proposed to use ferricium "potassium id" as a cyanide reagent.

Пример. мл анализируемого раствора, содержащего 1,35 мг тетратионата натри , помещают в мерную колбу емкостью 25 мл, в которую предварительно ввод т 2 мл 10%-ноГО -раствора феррицианида кали . Содержимое колбы выдерживают 5 мин, добавл ют 2 мл азотной кислоты (уд. вес 1,4) и довод т объем до метки. Оптическую плотность полученного раствора измер ют на фотоэлектроколориметре ФЭК-М с зеленым светофильтром в кювете толщиной 1 см. Количество тетратионата натри  «аход т по предварительно построенной калибровочной кривой.Example. A 1 mL solution to be analyzed containing 1.35 mg of sodium tetrathionate is placed in a 25 mL volumetric flask, into which 2 mL of a 10% potassium ferricyanide solution has been introduced. The contents of the flask were kept for 5 minutes, 2 ml of nitric acid (sp. Weight 1.4) were added and the volume was made up to the mark. The optical density of the resulting solution was measured on a FEK-M photoelectric colorimeter with a green light filter in a 1 cm-thick cuvette. The amount of sodium tetrathionate was taken according to a previously constructed calibration curve.
