4DescriptionAbstract A novel column solid phase extraction procedure was developed for the determination of Ni(II), Cu(II) and Zn(II) in water samples using newly synthesized reagent 1-(2-hydroxy-5-methoxybenzalidene)thiosemicarbazide for preconcentration and separation prior to FAAS using octylpolyethylene glycolphenyether (Triton x-100). The sorbed elements were subsequently eluted with 10 mL of 1 M HNO3 and the acid elutes were analysed by FAAS. Various parameters such as pH, amount of adsorbent, eluent type and volume, flow-rate of the sample solution, volume of the sample solution and matrix interference effect on the retention of the metal ions have been studied. The optimum pH for the sorption of above mentioned metal ions was about 7.00.5. The loading capacity of adsorbent for Ni(II), Cu(II) and Zn(II) were found to 28, 26 and 20 g mL-1 respectively. The limit of detections were found to be 3.6, 3.2 and 3.6 g mL-1 for Ni(II), Cu(II) and Zn(II) respectively by applying a preconcentration factor 83. Recoveries under optimum conditions were found to be 97.6 to 104% at the 98% confident level. The proposed enrichment method was applied successfully for the determination of metal ions in various water samples. The results were obtained are good agreement with reported method.
