| Abstract: |
| A method was established for the determination of 4 fluoroquinolones,ie.ciprofloxacin(CIP）,enrofloxacin(EN）,ofloxacin（OF） and norfloxacin(NOR) in aquatic products by capillary electrophoresis-electrochemical luminescence（CE-ECL） with modified gold nanoparticle enrichment.The conditions for enrichment and CE separation were studied,and the conditions for ECL detection were also investigated based on the principle of enhanced Ru（bpy）2+3 electrochemiluminescence.Under the optimal conditions,there were good linearities for the 4 analytes enriched with modified gold nanoparticles in the concentration range of 0.05-10.0 μmol/L.The detection limits（S/N=3） were low to 0.02 μmol/L and the enrichment times were 104-127.This method was used in the analysis of 4 analytes in actual eels samples with recoveries of 94.5%-112% and relative standard deviations（RSDs） not more than 6.3%. |
