AB  - A new cloud-point extraction (CPE) method was developed for the pre-concentration 
      and simultaneous determination of Sb(III) and B(III) by flame atomic absorption 
      spectrometry (FAAS). The method was based on complexation of Sb(III) and B(III) 
      with azomethine-H in the presence of cetylpyridinium chloride (CPC) as a 
      signal-enhancing agent, and then extraction into the micellar phase of Triton 
      X-114. Under optimised conditions, linear calibration was obtained for Sb(III) 
      and B(III) in the concentration ranges of 0.5-180 and 2.5-600 mug l(-1) with LODs 
      of 0.15 and 0.75 mug l(-1), respectively. Relative standard deviations (RSDs) (25 
      and 100 mug l(-1) of Sb(III) and B(III), n = 6) were in a range of 2.1-3.8% and 
      1.9-2.3%, respectively. Recoveries of spiked samples of Sb(III) and B(III) were 
      in the range of 98-103% and 99-102%, respectively. Measured values for Sb and B 
      in three standard reference materials were within the 95% confidence limit of the 
      certified values. Also, the method was used for the speciation of inorganic 
      antimony. Sb(III), Sb(V) and total Sb were measured in the presence of excess 
      boron before and after pre-reduction with an acidic mixture of KI-ascorbic acid. 
      The method was successfully applied to the simultaneous determination of total Sb 
      and B in selected beverage and dairy products.
