ABSTRACT
The measurement of element concentration in honey is generally a combination of a digestion procedure for dissolution of elements and a subsequent measurement of the dissolved elements. Prior to analysis, the honey samples must be decomposed with the appropriate methods procedure with digestates containing reduced amounts of carbon residues. In this work, the concentrations of twenty two chemical elements were determined in honey samples using HNO3 and H2O2 for mineralization. Trace element contents (Al, Ba, Co, Cr, Cu, Fe, Hg, Li, Mn, Ni, Sb, Sr, Pb, Tl, Th, U, V, Zn,) were determined by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), and major elements (Ca, K, Mg, Na) by Flame Atomic Absorption Spectrometry (F-AAS). The results showed that the microwave acid digestion with mixture HNO3:H2O2 = 9:1 was overall the best procedure for dissolution of elements from honey samples.
