Abstract
In this work, dispersive solid-phase extraction procedure was developed for trace cadmium determination before flame atomic absorption spectrometry (FAAS) measurement. Copper(II) based nanoflowers were synthesized to utilize as adsorbent for preconcentration of cadmium. The detection power of the spectrometric system was enhanced by placing a slotted quartz tube (SQT) onto the flame burner which increases the residence time of the analyte atoms in the flame region. The analytical performance of the developed system was evaluated with and without SQT equipment and the enhancement in detection power was calculated by the ratio of detection limits of CuNF-DSPE-FAAS (copper nanoflower based dispersive solid phase extraction-flame atomic absorption spectrometry) and FAAS system. Enhancement was determined as 73 and 104.3 times for CuNF-DSPE-FAAS and CuNF-DSPE-SQT-FAAS (CuNF-DSPE-slotted quartz tube-FAAS), respectively. Percent recovery results indicated the applicability of the developed method for the determination of trace cadmium.
