По селективности к свинцу на фоне макроколичеств хлорида никеля аниониты располагаются в ряд: Lewatit А365 ˃ Puromet MTS9841 ˃ Purolite S984 ˃ Purolite S985 ≥ Purolite А110. Повышение концентрации никеля в растворах отрицательно сказывается на емкости анионитов Lewatit А365 и MTS9841 по свинцу. Присутствие в растворах сульфата натрия (до концентрации по сульфат-иону 30 г/л) не оказывает отрицательного влияния на сорбцию свинца. Лучшие результаты по его извлечению обеспечиваются при сорбции из растворов с концентрацией никеля 100–120 г/л при рН не более 3,0–3,5. Установлено, что при пропускании через колонки с анионитами Lewatit А365 или Puromet MTS9841 модельного раствора, соответствующего по составу типичному хлоридно-сульфатному никелевому электролиту с концентрацией никеля 119 г/л, сульфат-иона (в форме сульфата натрия) 30 г/л и свинца 1,12 г/л, достигается более чем 1000-кратная очистка от примеси свинца первых 15 или 36 к.о. (колоночных объемов) раствора, пропущенного через аниониты Puromet MTS9841 или Lewatit А365 соответственно. Основное количество (93–99 %) поглощенного анионитами свинца десорби­руется дистиллированной водой при температуре 50 °С, а его остатки полностью десорбируются 1 М раствором NaOH.</p></abstract><trans-abstract xml:lang="en"><p>The removal of lead impurity from nickel chloride solutions by sorption on the weak-base anion exchange resins Lewatit A365, Purolite S984, Purolite S985, Puromet MTS9841, and Purolite A110 was studied.  All anion exchangers showed selective sorption of lead present as chloride complexes, although their selectivity differed. In terms of lead selectivity in the presence of a large excess of nickel chloride, the anion exchange resins were arranged in the following order: Lewatit A365 ˃ Puromet MTS9841 ˃ Purolite S984 ˃ Purolite S985 ≥ Purolite A110. An increase in nickel concentration in solution  adversely affected the lead capacity of Lewatit A365 and MTS9841. The presence of sodium sulfate in solution, up to a sulfate ion concentration of 30 g/L, had no adverse effect on lead sorption. The best lead removal was achieved by sorption from solutions containing 100–120 g/L nickel at pH not higher than 3.0–3.5. When a model solution corresponding in composition to a typical chloride-sulfate nickel electrolyte containing119 g/L nickel, 30 g/L sulfate ion as sodium sulfate, and 1.12 g/L lead was passed through columns packed with Lewatit A365 or Puromet MTS9841, more than 1000-fold purification from lead impurity was achieved for the first 15 or 36 column volumes of solution passed through Puromet MTS9841 or Lewatit A365, respectively. Most of the lead sorbed by the anion exchangers, 93–99 %, was desorbed with distilled water at 50 °C, while the residual lead was completely desorbed with a 1 M NaOH solution.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хлорид никеля</kwd><kwd>свинец</kwd><kwd>сульфат натрия</kwd><kwd>растворы</kwd><kwd>очистка</kwd><kwd>сорбция</kwd><kwd>десорбция</kwd><kwd>аниониты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nickel chloride</kwd><kwd>lead</kwd><kwd>sodium sulfate</kwd><kwd>solutions</kwd><kwd>purification</kwd><kwd>sorption</kwd><kwd>desorption</kwd><kwd>anion exchange resins</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Производство никеля и кобальта.
