AB  - A magnetic solid-phase extraction (MSPE) method was developed for simultaneous 
      preconcentrations of U(VI) and Th(IV) before their measurements by inductively 
      coupled plasma optical emission spectrometry (ICP-OES). The main idea of this 
      biotechnological application depends on the use of bacteria, thermophilic 
      Bacillus cereus SO-14, as a solid-phase biosorbent. It was immobilized to 
      gamma-Fe(2)O(3) magnetic nanoparticles and used for MSPE. Characterization of the 
      biosorbent was performed using the scanning electron microscope (SEM), the energy 
      dispersive X-ray (EDX) and Fourier transform infrared (FT-IR) spectroscopy. Also, 
      the the best conditions of experimental parameters were examined, and the 
      reliability of the method developed was verified by applying the certified 
      reference materials. Limit of detections (LODs) of the U(VI) and Th(IV) was 
      calculated as 0.008 and 0.013 ng mL(-1) respectively. Relative standard 
      deviations (RSDs) were found to be 1.6 and 2.4 %, respectively, for U(VI) and 
      Th(IV). R(2) was also calculated as 0.9991. Preconcentration factors were 
      achieved as 100 for both elements. It should be highlighted that LODs were 
      critically improved and the sensitivity of ICP-OES was enhanced.
