Abstract

A method was developed for the determination of trace amounts of Al species in water samples using the amberlite type XAD-4 resin. For this purpose, total dissolved Al, organically bonded Al and particulate Al in water samples taken from Karakaya dam lake (Malatya, Turkey) were determined by flame atomic absorption spectroscopy (FAAS) or graphite furnace atomic absorption spectroscopy (GFAAS) after an enrichment procedure. The total dissolved Al in the water samples was determined using 8-hydroxyquinoline as complexing reagent at pH 8 and amberlite type XAD-4 resins for the enrichment. The organically bonded Al species in the water samples were destroyed by the use of a photodecomposition apparatus and their levels were determined by FAAS after an enrichment procedure using amberlite type XAD-4 resin. The particulate Al in the water samples was determined by GFAAS after filtering them through a 0.45 \mu m membrane filter. According to our results, levels of total dissolved Al, organically bonded Al and particulate Al were between 1.98 and 3.76 mg/L, 55.3 and 67.1 \mu g/L, and 12.4 and 30.9 \mu g/L, respectively.
