Description
A novel sensitive and simple method for rapid and selective extraction, preconcentration and determination of mercury as its 2,2 diamino-4,42 bithiazole (DABTZ) complex by using octadecylsilica cartridges and spectrophotometry is presented. Extraction efficiency and the influence of flow rates of sample solution and eluent, pH, amount of DABTZ, type and least amount of eluent for elution of mercury complex from cartridges, break through volume and limit of detection were evaluated. Also the effects of various cationic and anionic interferences on percent recovery of mercury were studied. Average extraction efficiency >90% was obtained by elution of the cartridge with minimal amount of solvent in the presence of interferences. A preconcentration factor of 152 and a detection limit of 10.92 ng mL-1 were obtained. The method was applied to the recovery and determination of mercury in different water samples
