Description
Extraction of uranium from aqueous phosphoric acid by DEHPA/TOPO is carried out commercially and in pilot plants. The operating variables followed are temperature, concentration of phosphoric acid, and the ratio of DEHPA/TOPO. This study investigates the influence of these operating variables by the statistical method of 23 Factorial Design on extraction of uranium from phosphoric acid. The mathematical model suggested (K = 242.31-7.34C-4.784T+0.164C.T) predicts the effect of variables on the distribution ratio (extraction coefficient). The model is tested by a significance test and represented graphically. (author). 10 refs., 1 fig., 1 tab
