Özet
In this study, a rapid, sensitive and accurate analytical method was optimized for the determination of trace levels of cadmium (Cd) by fame atomic absorption spectrophotometry (FAAS) after antimony oxide nanoparticles (AO NPs)-based dispersive solid-phase extraction (DSPE). The AO-NPs were synthesized with a specifc microwave tem perature program, and they exhibited high purity and good surface morphology, making them appropriate sorbent material for the preconcentration/separation of a heavy metal. All experimental parameters afecting the extraction efciency were optimized univariately. Under the optimum operational conditions (35 mL sample volume, 0.75 mL of pH 8.0 bufer, 15 mg of sorbent, 5 s vortex and 100 µL of 1.0 M of HNO3), the limit of detection (LOD) and the limit of quantitation (LOQ) values were determined as 0.27 and 0.89 µg L−1, respectively. Thanks to the developed method, a 164.8-fold improvement in the sensitivity of the conventional FAAS system was achieved. Reusability tests showed that the AO-NPs can be employed 5 times. The feasibility of the method was confrmed by recovery tests with mul berry leaf tea matrices, and good recovery results between 77.6 and 115.8% were obtained using the matrix matching calibration method.
