The uranium is one of the main radioactive elements which, there is increasing need for development of simple and rapid monitoring of this element in the environment. The feasibility of thin-film solid phase extraction for alpha spectrometry for determination of uranium was investigated. Some parameters than can affect the extraction recovery and intensity of alpha spectrometry such as type of filter breakthrough volume, and amount of TOPO were studied. The calibration in the range of 2 μg to 400 μg of uranium was linear and the obtained LOD was 0.9 μg. The calibration and analytical sensitivity were better than XRF. The method was applied for determination of uranium in water samples.
