| By the way of orthogonal test, the extraction of rhodium by N-butyl isooctylamide from SnCl2-HCl-Rh system are investigated, introduced extraction rate calculation formula of evaluation of each group, in order to obtain the best experimental group. Experiments show that N-butyl iso- octylamide concentration is 1.5 mol/L, tributyl phosphate for the amount of 2 mL, concentration of HCl for 4 mol/L one-time extraction rate of rhodium was reached 99%. |
