Difusivitas uranil nitrat heksa hidrat dari fasa air ke fasa organik

Integral diffusivity of the uranium (VI) from the aqueous to the organic phase have been determined. In this methode an aqueous solution of the uranil nitrate hexa hidrate (UNH) was filled in a litle glass tube. The filled tube was placed in a litle vassel and flowed by the organic phase in a certain time unit. The organic phase was the TBP-KOERSENE in various mixture. The mixture was varied for 20%, 25%, 30%, 35% and 40% TBP. The ONH concentration was determined by beckman-25 spectrophotometer, at 412 nm. The evaluation of the data showed that the best value was on the mixture of the 35% TBP-65% KOERSENE i.e. D=2,16491 x 10 -5 flux molar.
