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) showed high sorption capacity for this element. This composite sorbent is planned to be used for uranium preconcentration for measuring environmental 236U/U ratios by Acceleration Mass Spectrometry (AMS) in bilateral cooperation with the University of Vienna. After the preliminary AMS results showing anthropogenic contamination in TiO-PAN sorbent, the preparation of titanium oxide was studied with a strong emphasis on elimination of this contamination. Several samples of titanium oxide were prepared from an organic uranium-free compound. These samples were studied using X-Ray Diffraction for their crystal structure and using selective sorption of nitrogen gas for their specific surface area. Their sorption properties were also evaluated. Presently we are focusing on finding a water source which is not anthropogenically contaminated in order to use this water for further experiments and on the following separation and concentration steps for AMS sample preparation.
