Abstract

Activated graphite@NiO nanoflowers was synthetized and characterized by field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) and Fourier transform infrared spectrometer (FTIR). It was used as adsorbent for dispersive solid-phase microextraction of Cu(II). The quantitative recovery values were found as pH 8.0, eluent 2.0 M HNO3, vortex time 30 s, adsorbent mass 20 mg, and preconcentration factor 80. The limits of detection and quantification were calculated as 4.23 µg L−1 and 14.1 µg L−1, respectively. The presented method was validated by the analyzing certified reference materials. It was sapplied to determination of copper contents of food and water samples.
