Özet

This study focuses on the development and application of a novel cellulose-modified nanocomposite (Co-ZnS@Cellulose) for the separation and preconcentration of analytes prior to detection by flame atomic absorption spectrometry (FAAS). The Co-ZnS@Cellulose adsorbent was employed in dispersive micro solid-phase extraction (d-µSPE) for the determination of Cd (II) and Pb (II) from complex matrices. The synthesized metal-doped ZnS nanocomposite, modified with cellulose, was characterized using FT-IR, XRD, FE-SEM, and EDX, confirming its structure and elemental composition. Key extraction parameters including pH, adsorbent dosage, sample volume, and eluent volume were optimized. The limits of detection were 0.025 mg kg⁻¹ for Cd and 0.015 mg kg⁻¹ for Pb, with a preconcentration factor of 30 and 40 respectively. The d-µSPE method was validated using two certified reference materials: 8433 Corn Bran (Canada) and TMDA-54–6 (Canada).
