Selenium Speciation in Karakaya Dam Lake's Water (Malatya-Turkey)

Concentrations of total inorganic selenium, Se(IV), Se(VI) and organically bonded selenium from samples of Karakaya dam lake\\\'s water were determined using ammonium pyrollidine dithio carbamate (APDC) as a chelating agent and subsequent adsorption on amberlite type XAD-8 resins. Eluted analytes are taken up in a matrix free acidic solution suitable for graphite furnace atomic absorption spectroscopy (GFAAS). According to our results, levels of the total inorganic selenium, Se(IV), Se(VI) and organically bonded selenium were found to be between 0.11 \\pm 0.01 and 0.17 \\pm 0.01 \mg/L, 0.07 \\pm 0.01 and 0.12 \\pm 0.01 \mg/L, 0.02 \\pm 0.01 and 0.05 \\pm 0.01 \mg/L, and 0.05 \\pm 0.01 and 0.08 \\pm 0.01 \mg/L, respectively.
