Properties of PAN-TBP extraction chromatographic material

Popis výsledku v původním jazyce

Three production routes of the preparation of a solid extractant based on tributylphosphate (TBP) embedded in the polyacrylonitrile matrix (PAN) have been studied. The method of direct PAN coagulation with TBP was found to be not viable due to the significant TBP solubility in the coagulation bath. The most suitable PAN-TBP solid extractant was prepared by the well-known impregnation method of ready-made neat PAN beads. The kinetics of uranium extraction from 3 mol L-1 HNO3, the effect of nitrate and nitric acids concentrations on the value of weight distribution coefficients D g as well as the uranium ?extraction isotherm? were determined for this material. Uranium extraction was rather fast, approximately 1 h was sufficient for the equilibrium achievement. Capacity for the uranium uptake, measured in batch experiments on PAN-TBP for 0.048 mol L-1 of uranium in 3 mol L-1 nitric acid, was found to be q = 0.363 mmol g-1 (58 % of the theoretical capacity). It was concluded that PAN-TBP m
