In this paper trace level uranium determination is reported using both the SPE-DLLME-FOLADS and the thermal lens spectroscopy methods and a comparision is made between them. In the first method, a combination of the extraction method for isolation and Uranium condensation before spectrophotometric measurements is used. in the second method, a He-Ne laser is used for generating the thermal lens inside the sample and this thermal lens is monitored by a He-Cd laser beam as a prob. Analyzing the oscilloscope collected data, revealed that in comparison with the SPE-DLLME-FOLADS method, the detection limit is higher in the Thermal lens spectroscopy method.
Keywords: Uranium, Extraction, Trace analysis, Thermal lens spectroscopy.
