Background:

• Cadmium (II) ions pose significant environmental and health risks.
• Effective preconcentration methods are crucial for accurate trace metal analysis.
• Developing sustainable and efficient sorbent materials is a key research area.

Purpose of the Study:

• To develop and characterize a novel sorbent material from Prunus Dulcis L. peels.
• To investigate the preconcentration efficiency of modified peels for Cadmium (II) ions.
• To evaluate the applicability of the method for real-world water sample analysis.

Main Methods:

• Modification of Prunus Dulcis L. peels with ethylenedinitrilo tetraacetic acid.
• Characterization using scanning electron microscopy-energy dispersive X-ray spectrometer and Fourier transform infrared spectrometer.
• Optimization of preconcentration parameters (pH, eluent, flow rate) and determination of adsorption capacity via Langmuir isotherm model.

Main Results:

• The modified Prunus Dulcis L. peels demonstrated excellent preconcentration of Cadmium (II) ions.
• High mean recovery (100.7 ± 1.5%) and low relative standard deviation (4.01%) were achieved.
• The sorbent exhibited a high adsorption capacity (277.8 mg g⁻¹) and a low limit of detection (0.216 µg L⁻¹).

Conclusions:

• Ethylenedinitrilo tetraacetic acid-modified Prunus Dulcis L. peels are a highly effective sorbent for Cadmium (II) preconcentration.
• The developed method is accurate and applicable for analyzing Cadmium (II) in environmental water samples.
• This study highlights the potential of agricultural waste as a sustainable material for environmental remediation and analysis.
