Abstract:

CuCo₂O₄ nanoparticle has been synthesized, characterized and firstly used as solid-phase extractant for the dispersive solid-phase extraction of Pb(II) in the presented work. The important parameters like pH of the working media, type of eluent solution and its volume, adsorbent amount, adsorption–desorption contact times, sample volume have been optimized. Lead (II) ions were quantitatively recovered on CuCo₂O₄ nanoparticle at pH 6.0 with 10 mg of adsorbent and eluted by using 2 mL of 1 M HCl. The influences of some cations and anions on the recoveries were also investigated. While the preconcentration factor was 25, the limit of detection was calculated as 6.5 µg/L. The method was checked by applying the method to certified reference material (TMDA-53.3). The method was successfully applied to various food, cigarette and water samples.
