Abstract
The method for the determination of flunixin residues in aquatic products is studied by HPLC-UV.Bovine milk is digested using β-glucuronidase.The enzyme digestion was extracted using acetonitrile,cleaned up with SPE column.The solution was analyzed by LC-UV using external standard method.The detection limit of this method is 5μg/kg for bovine milk and 40mg/kg for milk power.The results showed a good linear (r=0.9996) in the concentration range of 2.5-160.0μg/kg,the average recoveries for spiked standards (5.0μg/kg-40μg/kg)and(40.0μg/kg-100.0μg/kg) were 86.86％-100.32％,the relative standard deviations were 1.986％-2.295％ in bovine milk and milk powder.关键词
