Sorption-chromatographic
determination of tetracycline in milk and milk products
Abstract
The sorption of tetracycline by natural zeolite are systematically
studied (optimum process conditions, the distribution coefficient and sorption
capacity are determined). A method for determining a given antibiotic in milk
and milk products, based on the preliminary sorption concentration of
tetracycline by zeolite and subsequent determination of an analyte by HPLC with
UV detection are proposed. The advantages of the developed technique are low
cost analysis, simplicity and rapidity of execution. The technique can be used
in the practice of laboratories performing chemical analysis of foodstuffs.
Key words: tetracycline,
zeolite, sorption concentration, milk and milk products.
