Abstract
The authors previously reported the extraction kinetics of copper by benzoylacetone in a stirred transfer cell and during drop formation. The extraction kinetics of the same system during drop rise is discussed in this paper.
To interpret the influence of the concentrations of copper and hydrogen ion in the continuous phase and that of benzoylacetone in the dispersed phase on the extraction rate, a theoretical analysis was carried out, taking account of diffusion in a droplet and that accompanied by (1, l)-th order irreversible reaction in the continuous phase.
On the basis of the results of this theoretical analysis, the experimental results were examined and it was clarified that the reaction which forms chelating complex in the continuous phase can be treated as a pseudo-first order reaction with respect to benzoylacetone under the present experimental conditions.
