Özet

The present research explores the synthesis of cobalt-doped zinc oxide nanocomposite modified with activated magnetic multi-walled carbon nanotubes (Co-ZnO@mMWCNTs) for the separation, and preconcentration of Cd2 + and Pb2+. The nanocomposite was synthesized by hydrothermal process. The novel synthesized Co-ZnO@mMWCNTs nanocomposite exhibits a higher recovery rate of Cd2+ and Pb2+ compared to optimized conditions, achieving recovery rates of 97–100 %. With a detection limit of 0.037 mg L−1 for Cd2+ and 0.048 mg L−1 for Pb2+ and preconcentration, and the enhancement factor were 30 and 28.75 respectively. The proposed approach offers a novel nanocomposite-based platform with superior recovery, selectivity, and applicability compared to conventional methods. Real sample evaluation confirms their applicability to monitoring green and food sources, providing high selectivity and reproducibility.
