چکیده

The suitability of analytical protocol for determination of sulfonamides in honey was investigated. Sulfonamides were extracted from honey with acetate buffer, and cleaned up by solid phase extraction (SPE) procedure. The liquid chromatography (LC) separation was carried out on RP C18 column and sulfonamides were monitored with fluorescence detector, after pre-column derivatisation. Recoveries from spiked honey were above 80%, and detection limits were 0.1μg/kg for sulfacetamide and 0.2 μg/kg for sulfathiazole and sulfamethazine. The prepared procedure was used in the regular control of sulfonamide residues in honey.

Transfer of sulfamethazine from contaminated beeswax to honey.

A liquid chromatographic tandem mass spectrometric method for the determination of sulfa drugs in beeswax was developed. When performing residue control on beeswax intended for the fabrication of wax foundations, residues of sulfonamides were found. A migration test was set up to study whether sulfonamide-containing beeswax could lead to the contamination of honey. The higher the concentration ...
