To develop a novel carrier element-free coprecipitation method for the selective determination of trace Co(II) and Cu(II) in food and environmental matrices.
Developed a CEFC method using thiosemicarbazone-derived Schiff base ligand (MBITAH).
Optimized conditions for quantitative recovery at pH 7.0 with 1.5 mg ligand.
Validated with certified reference materials and spike/recovery tests.
Achieved limits of detection of 1.16 µg L⁻¹ for Co(II) and 0.79 µg L⁻¹ for Cu(II).
Preconcentration factor of 50 improved detection sensitivity using flame atomic absorption spectrometry (RSD ≤ 3.7%).
Demonstrated applicability in complex matrices like seawater, stream water, and food samples.
