Изобретение относитс к области аналитической химии.This invention relates to the field of analytical chemistry.
Известен способ экстракционного извлечени железа бензолом в виде комплекса с родамином 6Ж и галогенид-ионами из кислой среды.A known method for the extraction of iron from extraction with benzene in the form of a complex with rhodamine 6G and halide ions from an acidic medium.
Недостатком известного способа вл етс низка селективность и недостаточна степень извлечени железа.The disadvantage of this method is low selectivity and insufficient degree of iron recovery.
С целью увеличени степени и селективности извлечени по предлагаемому способу экстракцию ведут в виде хлоридного комплекса из растворов сол ной кислоты, причем извлечение железа провод т предпочтительно из 7н. раствора сол ной кислоты.In order to increase the degree and selectivity of the extraction according to the proposed method, extraction is carried out in the form of a chloride complex from hydrochloric acid solutions, moreover, iron is extracted from preferably 7N. hydrochloric acid solution.
Пример. В длительную воронку внос т исследумый раствор железа, добавлением 12н. сол ной кислоты создают кислотность водной фазы, равную 7н., приливают 0,25 мг-Ю- М водного раствора родамина 6Ж, добавл ют Example. An investigative solution of iron is added to the long funnel by adding 12N. hydrochloric acid creates an acidity of the aqueous phase, equal to 7n., 0.25 mg-10-M aqueous solution of rhodamine 6G is added, add
6 мл бензола и экстрагируют в течение 1 мин. После разделени фаз экстракт центрифугируют в течение 3 мин нри 3000 об/мин и измер ют оптическую плотность на спектрофотометре или фотоэлектрокалориметре. Количество железа наход т по калибровочному графику.6 ml of benzene and extracted for 1 min. After separation of the phases, the extract is centrifuged for 3 minutes at 3000 rpm and the optical density is measured on a spectrophotometer or photoelectrocalorimeter. The amount of iron is found in a calibration graph.
