Abstract

Способ экстракции ионов железа 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 (В) к органической (О) фазе В:О≥3 для Fe (III) и В:О=3-6 для Fe (II) при рН 2-3 для Fe (III) и 9-11 для Fe (II) и Fe (III) и времени экстракции 1-3 мин для Fe (III) и не более 60 мин для Fe (II).A method of extracting iron ions from an aqueous solution, including contacting the extractant and the solution, mixing the mixture, settling and separation of the phases, characterized in that the extraction is carried out from the aqueous solution with vegetable oils at a ratio of aqueous (B) to organic (O) phase B: O≥3 for Fe (III) and B: O = 3-6 for Fe (II) at pH 2-3 for Fe (III) and 9-11 for Fe (II) and Fe (III) and extraction time 1-3 min for Fe (III) and not more than 60 min for Fe (II).
