Ciprofloxacin residue analysis in pangasius by electrochemical voltammetry
Author(s): Nguyen Phuoc Minh
Abstract: A simple, sensitive electrochemical method (voltammetry) for the detection and quantification of ciprofloxacin in Pangasius has been developed. The assay consisted of recovery, limit of detection, analyzed ciprofloxacin concentration, regression equation, correlation coefficientÂ when examining ciprofloxacin stock solution added at 1.52745, mg/L, 1.0183mg/L, and 0.50915 mg/L. Results show high recovery (74.5, 77.5, and 78.2% in equivalent), low LoD (48.7, 20.1, 54.9 Âµg/L in equivalent). Then Pangasius fillets are sampled in local markets to confirm the detection of the analysis.Â This method is sufficiently sensitive for screening analysis strongly supporting for other confirmation ones that small and medium enterprises of fish processing can be approached.
