PLATINUM AND PALLADIUM EXTRACTION SEPARATION PROCESS |
摘要 |
<p>precious metal technology. SUBSTANCE: process is accomplished by selectively extracting platinum from aqueous phase into organic phase using as extractant solutions of compounds of formula Ar2P(O)(CH2)nNR2 in organic solvent. 0.01 M dichloroethane solutions of Ar2P(O)(CH2)nNR2 can also be used. Extraction of platinum and palladium can be performed from 4 M hydrogen chloride solutions. EFFECT: increased separation selectivity. 3 cl, 2 dwg, 2 tbl, 10 ex</p> |
