A comparative study of kinetic models for the extraction of uranium by strong-base anion-exchange resins
Fleming, C.A. and Nicol, M.J. (1980) A comparative study of kinetic models for the extraction of uranium by strong-base anion-exchange resins. Journal of the South African Institute of Mining and Metallurgy, 80 (2). pp. 89-99.
This paper, examines the kinetics of the extraction of uranium from acid sulphate solutions by strong-base anion-exchange resins. Parameters such as the concentration of uranium in solution, the agitation of the resin beads in solution, the size of the resin beads, and the degree of cross-linking within the resin matrix were varied, and the effects on the kinetics are reported. The applicability, of various empirical kinetic models to the description of the data is assessed, and an attempt is made at the modelling of the rate data in terms of established theories about the diffusion of ions through films of stagnant liquid and through spherical beads of resin.
