Characterization and preparation of TiO-PAN sorbent
Original language description
The uranium separation from natural waters was studied at the Department of Nuclear Chemistry in late 80's and early 90's. TiO-PAN sorbent (titanium dioxide embedded in polyacrylonitrile) embodied high sorption capacity for uranium. The purpose of this project was the thorough characterization of TiO-PAN sorbent with dynamic and static experiments which include kinetic experiments, sorption isotherm, effect of several ions (Ca2+; Mg2+; Fe3+; NO3 -; SO42-;Cl-; CO32-) (V/m = 500 ml/g). It was found that CO32-, SO42- and NO3- ions have a positive effect on uranium sorption and on the other hand Cl- ions have a negative sorption effect. Specific surface area was measured and compared with results gained in 2001. The uranium concentrations were determined by Time Resolved Laser Induces Fluorescence Spectrometry (TRLFS) which allows us to measure uranium concentrations up to ppb level. A strong influence of Cl- ions present in the solutions was seen, thus the calibration of TRLFS has to be m
