Изобретение относитс к области переработки растворов, содержащих ионы фтора, в частности технологических растворов, содержащих ионы фтора и неорганических кислот.This invention relates to the field of processing solutions containing fluorine ions, in particular process solutions containing fluorine ions and inorganic acids.
Известен способ переработки растворов, содержащих ионы фтора и неорганических кислот, путем экстракции ионов фтора органическим экстрагентом. В качестве такого экстрагента используют, например, триалкиламины .There is a method of processing solutions containing fluoride ions and inorganic acids, by extracting fluoride ions with an organic extractant. As such an extractant, for example, trialkylamines are used.
Существенным недостатком известного способа вл етс низка степень извлечени фтора , не превыщающа 50% при однократной экстракции.A significant disadvantage of the known process is the low degree of fluorine recovery, not exceeding 50% with a single extraction.
Дл повыщени степени извлечени фтора предлагаетс в качестве экстрагента использовать сульфоксиды, например сульфоксиды, выдел емые из продуктов переработки нефти.To increase the degree of fluorine recovery, it is proposed to use sulfoxides, such as sulfoxides, derived from petroleum products as an extractant.
Ири использовании указанного экстрагента степень извлечени фтора существенно увеличиваетс и достигает при однократной экстракции 58-75% (в зависимости от состава исходного раствора).Using this extractant, the degree of fluorine extraction increases significantly and reaches 58-75% with a single extraction (depending on the composition of the initial solution).

Пример. Растворы, содерл ащие фтор и неорганические кислоты, контактируют с сульфоксидом при соотнощении объемов органической и водной фазы 1:1. Продолжительность контактировани 5 мин с последующим 30-тиминутным расслаиванием.Example. The solutions containing fluorine and inorganic acids are contacted with the sulfoxide at a 1: 1 ratio of the organic and aqueous phases. The duration of contact is 5 minutes, followed by 30 minutes of delamination.
Результаты опытов приведены в таблице.The results of the experiments are given in the table.
