title: A rapid fluorimetric screening method for chlortetracycline, oxytetracycline and tetracycline in pig meat and kidney tissues.
abstract: A rapid fluorimetric screening method for chlortetracycline, oxytetracycline and tetracycline in pig meat and kidney tissues is described. After sonication-aided extraction with ethyl acetate, the extract is cleaned and concentrated by means of solid-phase extraction using an aromatic sulphonic acid cation-exchange column. Subsequent screening is carried out by fluorimetry. The detection level is estimated to be about 0.05 mg kg-1 for oxytetracycline, 0.1 mg kg-1 for chlortetracycline and 0.2 mg kg-1 for tetracycline.
