Extraction of platinum(IV) with supported liquid membrane containing trioctylamine carrier
Conference

OSTI ID:5751165
A trioctylamine(TOA)-supported liquid membrane was applied to the separation and concentration of platinum. Platinum was transported and concentrated from the hydrochloric acid solution to the alkaline solution across the membrane. The effects of the concentration of TOA and those of platinum in the feed and stripping solutions on the permeation rate are clarified. The mechanism of platinum transport through the membrane is discussed based on a simple permeation model.
