Abstract
1. СПОСОБ ИЗВЛЕЧЕНИЯ ОСМИЯ ИЗ СЕРНОКИСЛЫХ РАСТВОРОВ, включающий сорбцию твердым, сорбентом и последуюг щую термообработку, отличающийс тем, что, с целью повышени степени извлечени осми и обеспечени возможности многократного использовани сорбента, сорбцию ведут из растворов с концентрацией серной кислоты 200-500 г/л, а в качестве сорбента используют сернокислый свинец. 2. Способ по п. 1, отличающийс тем, что сорбцию ведут в течение 3-4 ч при соотношении 1:20 - 30.1. METHOD FOR EXTRACTING OSMIA FROM SULFUR ACID SOLUTIONS, including sorption with a solid, sorbent and subsequent heat treatment, characterized in that, in order to increase the recovery of osmium and ensure the possibility of repeated use of the sorbent, sorption is carried out from solutions with a concentration of sulfuric acid 200-500 g / l, and lead sulfate is used as a sorbent. 2. A method according to claim 1, characterized in that the sorption is carried out for 3-4 hours at a ratio of 1:20 - 30.
