Abstract
Using Pt-191 radiotracer, the liquid-liquid extraction behaviour of Pt (IV) from HCl medium with rubeanic acid in tributyl phosphate (TBP), w ith tributyl phosphate and with thenoyltrifluoroacetone (TTA) in n-but yl alcohol-acetophenone was examined. The effects of acidity, shaking time and Pt concentration were studied, in addition to the subsequent back-extraction. Optimum extraction recoveries were found when using 3 M HCl for TBP and 4 M HCl for TTA. Ammonia solution (2 M) yielded the best recovery for back-extraction. In order to evaluate the procedure in the presence of a matrix, some biological and environmental materi als were spiked with Pt-191 and the recovery of the radiotracer in the different steps was investigated.
