Description
В насто щее врем слабокислые никелевые и кобальтовые хлоридные растворы очищают от цинка путем ионного обмена.At present, weakly acidic nickel and cobalt chloride solutions are purified from zinc by ion exchange.
Предлагаетс способ более полного отделени цинка от сульфатнохлоридных никелевых и кобальтовых растворов, а именно - анионитом АВ17 при рН 1-6.A method for more complete separation of zinc from sulfate-chloride nickel and cobalt solutions, namely AB17 anion exchanger at pH 1-6, is proposed.
Способ бсущ,ествл етс в Два цикла. СнаЧала йикелёвьш или кобальтовый суЛьфатнохйорйдный слабокислый раствор пропускают через колонну с заданной скоростью до по В итёни в Ьытёкйющем из колонны растворе цинка в количестве, Определенном глубиной бчистки. атем регенерируют анйонит. Полна The method is in two cycles. In the beginning, a nickel-like or cobalt sulfate-hopping weakly acidic solution is passed through the column at a predetermined rate up to the B branch in an amount of zinc solution, which flows from the column, in a quantity determined by the cleaning depth. then regenerate anionite. Is full
регенераци его достигаетс промыванием водой .its regeneration is achieved by washing with water.
При регенерации раствор собираетс по фракци м. Первые фракции, содержащие больщое количество цинка, вл ютс оборотными . Потери никел и кобальта при этом способе не превышают 0,2-0,3% от количества никел , очищенного от цинка.During regeneration, the solution is collected in fractions. The first fractions containing a large amount of zinc are circulating. The loss of nickel and cobalt with this method does not exceed 0.2-0.3% of the amount of nickel purified from zinc.
