Natural Deep Eutectic Solvents Impregnated Graphene Oxide as an effective adsorbent for Dispersive Solid Phase Microextraction of Cd(II) From Environmental Samples

Abstract

A sensitive and selective dispersive solid phase microextraction procedure was developed by synthesizing NaDES impregnated Graphene oxide nanocomposite (GO@NaDES) for the determination of trace amounts of cadmium prior to high-resolution continuum source flame atomic absorption spectrometry (HR-CS-FAAS) measurement. The detection limit, preconcentration factor, enrichment factor, and relative standard deviation were determined as 0.613 µg L− 1, 30, 30.3 and 4.0-5.5%, respectively. The method was successfully applied to natural and water samples and the amount of Cd was measured effectively. The d-SPME method developed will contribute to the literature as a practical, environmentally friendly and inexpensive method that can be performed in a short time of about 15 minutes, including analysis for Cd(II) analysis at the trace level in environmental water and food samples.
