Abstract

Способ экстракции ионов свинца из водного раствора, включающий контактирование экстрагента и раствора, перемешивание смеси, отстаивание и разделение фаз, отличающийся тем, что экстракцию осуществляют из водного раствора растительными маслами при отношении водной (B) к органической (O) фазе B:O≤7, pH 9-13 и регулировании величины pH в течение не более 1,5 ч.A method for extracting lead ions from an aqueous solution, including contacting the extractant and the solution, stirring the mixture, settling and separating the phases, characterized in that the extraction is carried out from an aqueous solution with vegetable oils at a ratio of aqueous (B) to organic (O) phase B: O≤7 , pH 9-13 and adjusting the pH value for no more than 1.5 hours.
