Abstract :The synthesis and characterization of ethylenediaminetetraacetic acid immobilized activated carbon cloth was performed in the present work. It was used for preconcentration-separation of leadinsert ignore into journalissuearticles values(II);, cobaltinsert ignore into journalissuearticles values(II);, and nickelinsert ignore into journalissuearticles values(II); at trace levels as an adsorbent. Factors including pH, concentration and volume of eluent, sample and eluent flow rates, sample volume, and effect of coexisting ions on the solid phase extraction of analytes were examined. The preconcentration factor was 50. The detection limits for Pbinsert ignore into journalissuearticles values(II);, Coinsert ignore into journalissuearticles values(II);, and Niinsert ignore into journalissuearticles values(II); were 4.39, 0.99 and 0.91 $\mu $g L$^{-1}$, respectively. The adsorption capacity for Pbinsert ignore into journalissuearticles values(II);, Coinsert ignore into journalissuearticles values(II);, and Niinsert ignore into journalissuearticles values(II); ions was found as 11.0, 11.2, and 10.2 mg g$^{-1}$, respectively. The validation of the method was performed by the analysis of certified reference materials insert ignore into journalissuearticles values(SPS-WW2 wastewater and BCR-146R sewage sludge amended soil insert ignore into journalissuearticles values(industrial origin););. The method was successfully applied for the determination of lead, cobalt, and nickel in fertilizer and water samples from Kayseri, Turkey.
