developed. The Hg(II) ions were retained on a mini-column packed with agar powder modified with 2-mercaptobenzimidazole at a flow rate of 6 mL min(-1). The retained Hg(II) ions were eluted with 3 mol L(-1) solution of HCl and measured by cold vapor atomic absorption spectrometry (CV-AAS). The effect of different variables such as pH, sample flow rate, amounts of 2-mercaptobenzimidazole loaded on agar and SnCl(2) concentration was investigated and optimum conditions were established. The calibration curve was linear in the range of 0.040-2.40 ng mL(-1) with r=0.9994 (n=8). The limit of detection based on three times the standard deviation (3S(b)) (n=10) obtained under optimum conditions was 0.02 ng mL(-1). The relative standard deviation (R.S.D.) for the determination of 0.4 and 2.0 ng mL(-1) of Hg(II) was 2.6 and 1.9% (n=8), respectively. The method was successfully applied to determine Hg(II) in water, wastewater and fish samples.
