Abstract

1. Способ извлечения рения из урансодержащих растворов сорбцией на анионитах, отличающийся тем, что перед сорбцией вводят фульвеновые кислоты до создания их концентрации в растворе 25÷300 мг/л, а сорбцию рения ведут в их присутствии при значении pH раствора 2,8÷3,5 причем сорбцию проводят на слабоосновных и сильноосновных анионитах.2. Способ извлечения рения из урансодержащих растворов по п.1, отличающийся тем, что концентрация фульвеновых кислот составляет 50÷100 мг/л.1. The method of extraction of rhenium from uranium-containing solutions by sorption on anion exchangers, characterized in that fulvenic acids are introduced before sorption to create their concentration in the solution 25–300 mg / l, and rhenium sorption is carried out in their presence at a pH of 2.8–3 , 5 and sorption is carried out on weakly basic and strongly basic anion exchangers. 2. The method for extracting rhenium from uranium-containing solutions according to claim 1, characterized in that the concentration of fulvenic acids is 50-100 mg / L.
