Abstract
1. Способ регенерации анионита в сульфатной форме после насыщения его молибденом в результате сорбции молибдена из раствора, включающий десорбцию молибдена аммиачно-сульфатным раствором, последующую конверсию анионита из гидроксильной в сульфатную форму путем обработки анионита сернокислым раствором, отличающийся тем, что, с целью удешевления процесса за счет сокращения реагентов на обработку анионита при сохранении высокой степени его регенерации, конверсию анионита осуществляют в две стадии, причем на первую стадию подают маточный раствор со стадии сорбции, а на второй стадии используют маточный раствор, подкисленный серной кислотой, в количестве 20 - 50 г/л.2. Способ по п.1, отличающийся тем, что на десорбцию молибдена подают раствор после первой стадии конверсии анионита.1. Method of regenerating anion exchanger in sulphate form after saturating it with molybdenum as a result of molybdenum sorption from solution, including desorbing molybdenum with ammonium sulphate solution, subsequent conversion of anion exchanger from hydroxyl to sulphate form by treating the anion exchanger with sulphate solution, characterized in that, in order to reduce the process due to the reduction of reagents for the treatment of anion exchange resin while maintaining a high degree of its regeneration, the conversion of the anion exchange resin is carried out in two stages, and the uterine is supplied to the first stage the solution from the sorption stage, and in the second stage, the mother liquor acidified with sulfuric acid is used in the amount of 20-50 g / l. The method according to claim 1, characterized in that the solution is fed to the desorption of molybdenum after the first stage of anion conversion.
