Abstract  

Cadmium in water was preconcentrated by adsorption on activated carbon after complexation with potassium ethyl xanthate. The recovery was >90% in the concentration range 10 g l–1 to 500 g l–1 with an enrichment factor of 1000. The method was employed for the analysis of cadmium in spiked water samples, by NAA and AAS. The standard deviation and relative mean error was 0.062 and 0.015, respectively.
