Simple and Robust GFAAS Methods for Determination of As, Cd, and Pb in Hemp Products Using Different Sample Preparation Strategies

Simultaneous determination of lead and copper in Polygonatum kingianum by ICP OES combined with natural deep eutectic solvent-based magnetic dispersive micro solid phase extraction

“…At present, the atomic spectrometric analysis methods used in the determination of metal elements include inductively coupled plasma optical emission spectrometry (ICP OES), 4,5 inductively coupled plasma mass spectrometry (ICP-MS), 6,7 flame atomic absorption spectrometry (FAAS), 8,9 graphite furnace atomic absorption spectrometry (GFAAS), 10,11 electrothermal atomic absorption spectrometry (ETAAS) 12,13 and so on. However, due to the complexity of the sample matrix and the difficulty of detecting trace contaminant elements, the combination of advanced sample separation and preconcentration methods and atomic spectroscopy is a more effective strategy for the analysis of trace elements.…”
