Abstract :

This research aimed to determine the concentration of chloramphenicol in shrimp using the standard addition method based on the diazotization reaction using Zn powder as a reducing agent of chloramphenicol, followed by the use of N-(1-naphthyl) ethylenediamine dihydrochloride as a coupling agent and measured at 565 nm. Based on the test, the shrimp sample was found to contain 1964.91 mg/kg of chloramphenicol and it exceeded the requirements set by the European Commission which was 0,15 mg/kg. The limit of detection (LOD) value is 0.19 mg/mL and the limit of quantitation (LOQ) value is 0.64 mg/mL. The correlation coefficient (R²) was 0.9991 for the concentration range of 0-50 ppm. The analysis of the results showed that the %recovery in shrimp analysis using this method was 87.41%-107.73% with an average of 109.38%.
