Description
Изобретение касаетс так называемой дисперсионной экстракции, при помощи которой соединени железа извлекаютс из водной фазыThe invention relates to the so-called dispersive extraction, by which iron compounds are extracted from the aqueous phase.
Известные способы выделени осадков из водной фазы (пеннан хроматографи , флотаци ) требуют использовани воздуха или реагентов-пенообразователей . Известен также способ выделени осадков из твердой фазы с помощью обменной жидкостной экстракции, однако расход экстрагирующих реагентов при псиользоваиии этого способа весьма велик.Known methods for separating precipitates from the aqueous phase (pennan chromatography, flotation) require the use of air or frother reagents. There is also known a method of separating precipitates from the solid phase using exchange solvent extraction, however, the consumption of extracting reagents during the psychotherapy of this method is quite large.
Предлагаемый способ извлечени соединений железа из водной фаshi отличаетс от известных тем, что соединени железа извлекают в коллоидной форме, добавл предварительно щелочьСиособ позвол ет упростить процесс и значительно сократить необходимое дл экстракции количество реагента, в данном случае карбоновых кислот.The proposed method for extracting iron compounds from aqueous phosphorus differs from the known ones in that iron compounds are recovered in colloidal form by adding alkali to the alkali beforehand to simplify the process and significantly reduce the amount of reagent needed for extraction, in this case carboxylic acids.
Существо способа состоит в следующем.The essence of the method is as follows.
К водному раствору, содержащему соли трехвалентного железа, добавл ют осадитель, например раствор щелочи, дл образовани коллоидного осадка гидроокиси железа (рН раствора -- 6). Полученный гидрозоль смещивают с инертным растворителем, например керосином, содержащим небольщие дозы карбоновых кислот, примерно в количестве 0.01 мол на 1 моль железа.A precipitating agent, such as an alkali solution, is added to an aqueous solution containing ferric salts to form a colloidal precipitate of iron hydroxide (pH of the solution is 6). The resulting hydrosol is shifted with an inert solvent, such as kerosene, containing small doses of carboxylic acids, in an amount of approximately 0.01 mol per 1 mole of iron.
Основна масса осадка в виде грубодисперсных коллоидных частиц переходит в органическую фазу, от которой может быть отделена обычными приемами: фильтрованием, центрифугированием, реэкстракцией водными растворами минеральных кислот.The bulk of the sediment in the form of coarse colloidal particles passes into the organic phase, from which it can be separated by conventional methods: filtration, centrifugation, reextraction with aqueous solutions of mineral acids.
В таблице приведены результаты, полученные при дисперсионной экстрации трехвалентного железа из -водных растворов.The table shows the results obtained when the dispersion extraction of ferric iron from aqueous solutions.
При-повторной обработке водной фазы () описанным способом извлечение железа достигает 99,90/0 (0,003 г/л в водной фазе).With the re-treatment of the aqueous phase () in the manner described, the extraction of iron reaches 99.90 / 0 (0.003 g / l in the aqueous phase).
Дисперсионна экстраци может найти практическое применение в химической технологии и неорганической химии.Dispersion extraction can find practical application in chemical technology and inorganic chemistry.
Предмет изобретени Subject invention
Способ извлечени соединений железа из водной фазы экстракцией: с помощью органических жидкостей, например смеси карбоновых кислот с керосином, отличающийс тем, что, с целью уменьшени расхода реагентов, соединени железа извлекают в присутствии щелочей в форме коллоидных осадков с последующим отделением этих осадков от жидкой фазы известными приемами.Extraction of iron compounds from the aqueous phase: using organic liquids, such as mixtures of carboxylic acids with kerosene, characterized in that, in order to reduce the consumption of reagents, iron compounds are extracted in the presence of alkalis in the form of colloidal precipitates, followed by separation of these precipitates from the liquid phase famous tricks.
