In the solvent extraction of nickel from aqueous ammonium nitrate solution with anti-2-hydroxy-5-nonylacetophenone oxime in MSB 210, measurements of initial extraction rate using a stirred transfer cell were carried out at 30°. The extraction rate was found to be described by the rate expressionIn the solvent extraction of nickel from aqueous ammonium nitrate solution with anti-2-hydroxy-5-nonylacetophenone oxime in MSB 210, measurements of initial extraction rate using a stirred transfer cell were carried out at 30°. The extraction rate was found to be described by the rate expression N=1.1×10-10[Ni2+][HR]/[H+]/1+1.1×10-6[Ni2+]/[H+]which was derived on the assumption that the elementary reaction step between the intermediate complex adsorbed at the interface and free extractant molecule in the aqueous phase is rate-determining. The reason why this step is rate-determining was inferred.
