| Abstract |
Systematic studies were carried out to investigate the extraction kinetics of cobalt by di-2-ethyl-hexyl phosphoric acid in kerosene using a single drop cell. The extraction rates were increased with increasing pH and cobalt concentration in the aqueous phase. The concentration of D₂EHPA had a little effect on the extraction rate within the experimental range. Extraction kinetics correlated well with the Handlos-Baron model coupled with an intermediate complex formation at the organic-aqueous interface |
