Abstract:Egg samples are dissolved in 0.1 mol/L Na2EDTA-Mcllvaine buffer solutions, the sample solution are cleaned up by both Oasis HLB SPE cartridge and carbolic acid anion exchange cartridge and then were determined by liquid chromatography-UV detection at 355 nm. At 0.010- 0.200 mg/kg fortification levels, recoveries are 70 % - 110 %, while coefficients of variation within 13%. Limit of detection is 0.005 mg/kg for terramycin.
Keywords:egg  terramycin  solid-phase extraction  liquid chrornatography-UV detection
