AB  - A new method was developed for the simultaneous speciation of inorganic selenium 
      and antimony in water by electrothermal vaporization inductively coupled plasma 
      mass spectrometry (ETV-ICP-MS) following selective cloud point extraction (CPE). 
      The method is based on the fact that Se(IV) and Sb(III) could form complexes with 
      diethyldithiocarbamate (DDTC) at pH 6.00, and the complexes were quantitatively 
      extracted into the non-ionic surfactant-rich phase of 
      octylphenoxypolyethoxyethanol (Triton X-114), whereas the Se(VI) and Sb(V) 
      remained as free species in aqueous solutions. Sb(III) and Se(IV) in concentrate 
      were determined by ETV-ICP-MS after proper disposal. The total Se and total Sb 
      were determined by the same protocol after Se(VI) and Sb(V) were reduced by 
      l-cysteine, and Se(VI) and Sb(V) concentrations were obtained by respectively 
      subtracting Se(IV) and Sb(III) from the total Se and the total Sb. Under the 
      optimized conditions, the limits of detection (LODs) were 0.05 microg L(-1) for 
      Se(IV) and 0.03 microg L(-1) for Sb(III), the relative standard deviations (RSDs) 
      were 3.5% for Se(IV) and 4.2% for Sb(III) (C=1.00 microg L(-1), n=5). The 
      proposed method was applied to the speciation of inorganic selenium and antimony 
      in different water samples with satisfactory results.
