Title
Extraction Kinetics of Cobalt by D2EHPA in a Single Drop Cell
이준동J . D . Lee, 손헌준H . J . Sohn, 강탁T . Kang
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
