“…17 The composition of honey can serve as an indicator of pollution in the environment or its specic origin. 18 The commonly employed techniques for analyzing heavy metal ions in honey include inductively coupled plasma (ICP)-atomic emission spectroscopy, 19 ICP-optical emission spectroscopy, [20][21][22][23] ICP-mass spectrometry, 19,21,24 ame atomic absorption spectrometry (FAAS), [25][26][27][28] and graphite furnace atomic absorption spectrometry. 29,30 Considering the problems of trace analysis in real samples and matrix effect, a preconcentration stage plays an effective role in the analysis.…”
