Abstract

The kinetics of extraction of U(IV) by TBP in kerosene was investigated using a stirred Lewis cell. The effect of the different parameters affecting the extraction rate as well as temperature were separately investigated. The rate equation deduced from the experimental results show that the extraction of U(IV) is first order dependent on TBP concentration while it is of zero order with respect to U(IV), H+, NO −3 and HNO3 concentrations. The data obtained show that the extraction process is governed by chemical reactions taking place at teh interface.
