To retain traces of Cu and Zn and separate them from fructose and glucose, sorption properties of different cation exchangers were examined.
Then, for selected one, i.e., strongly acidic cation-exchange resin Dowex 50W × 8-400, conditions of recovery of enriched Cu and Zn traces was assessed.
The analytical performance of the SPE pre-concentration/separation procedure was assessed. The developed method was used to determine the content of Cu and Zn in commercially available and freshly ripened honey samples coming from the Lower Silesia region of Poland.
