An Analytical Method for Detecting the Content of Metallic Elements in Honey Collected from Henan, China: A Systematic Investigation with ICP-AES

摘要

In this study, the method for determining ten elements (including K, Na, Ca, Mg, Fe, Mn, Cu, Zn, Pb, and Cd) was designed. With this method, we evaluated 15 honey samples, including three kinds of honey collected from 11 different geographic sites in Henan province of China, with inductively coupled plasma atomic emission spectrometry (ICP-AES). The obtained detecting data were analysed with principal component analysis, correlation analysis, and cluster analysis techniques. The results showed that the recovery is in the range of 93.0?107.0?%, and the relative standard deviations (RSDs) were all below 5.89?%, which indicates that the current analytical method is dependable for the detection of metallic elements in honey.
