Determination of thiabendazole residues in meat by HPLC using ultraviolet and fluorometric detection

Abstract: An HPLC method is described for the residue analysis of thiabendazole in meat. The recovery varies from 62 to 75%. Thiabendazole is extracted from the tissue using 3 mol HCl, eluted from the Extrelut-20 column with dichloromethane and then injected onto a C18 column. The optimum conditions for detection are described using ultraviolet and fluorescence spectroscopy. The sensitivity is such that thiabendazole can be determined at a level of 5 micrograms/kg meat. The absolute detection limit with fluorometry is 1… Show more

“…Herbicides [37][38][39], and fungicides [40][41][42][43] have been also analysed by direct fluorimetry. In most cases, the pesticide fluorimetric detection has been performed on solid substrates by thin layer chromatography (TLC) [32,44] or in combination with dynamic systems including HPLC [20,[22][23][24][25][26][27][28][29][30][31][33][34][35][36][37][40][41][42][45][46][47][48] and flow injection analysis (FIA) [21,43]. For instance Garcia and Aaron [43] applied FIA with spectrofluorimetric detection for determining fungicides such as thiabendazole and fuberidazole at the ng ml -1 level in river waters (Fig.…”

“…Several methods have been used for the qualitative and quantitative analyses of anthelmintics, including LC-MS/MS, 6,7 GC-MS, 8,9 CE-ESI-MS, 10 gas-liquid chromatography (GLC) coupled with an electron-capture detector (ESD), 11 turbidimetry 12 and voltammetry. 13 Moreover, there are several literature reports on the determination of anthelmintics using HPLC combined with uorescence (FL), 14,15 UV spectrophotometric [16][17][18][19][20] or diode array (DAD) detection. 21,22 The evaporative light scattering detector (ELSD) has been used increasingly in recent years, [23][24][25] particularly for compounds lacking chromophores.…”

“…Η ανάκτηση της μεθόδου κυμαίνεται σε 63-66% ενώ το όριο ανίχνευσης βρίσκεται στα 5 ng/ml. Οι ίδιοι ερευνητές την ίδια χρονιά προτείνουν εναλλακτική μέθοδο για την ίδια ανάλυση,(Wyhowski de Bukanski et al, 1991a). Στην περίπτωση όμως αυτή το όριο ανίχνευσης ανέρχεται 50 ng/ml.…”
