Selective extraction of palladium from acidic nitrate solutions with thiamacrocycles-synergized dinonylnaphtalenesulfonic acid systems
Résumé
Thiamacrocycles-synergized sulfonic acid extraction systems have been studied for removing traces of palladium from nitric acid solutions. The influence of the concentration of nitric acid, HDNNS, and thiamacrocycle were studied. Then different thiamacrocycles, with various cavity size and with or without substituent were evaluated. Influences on the extraction and stripping behavior is discussed.
