Abstract
This research aims to determine the effect of chloramphenicol concentration in shrimp toward the value of enrichment factor (EF) in the adsorption-desorption process using Molecularly Imprinted Polymer (MIP) as adsorbent. The enrichment factor describes how much analyte concentration is transferred from the sample to the solvent. In this research, the highest enrichment factor (EF) value was obtuined for chloramphenicol concentration of 50 ppm which was 120,086%. The Scanning Electron Microscope (SEM) analysis showed that the sizes of Blank Polymer (PB), Non-Imprinted Polymer (NIP), and Molecularly Imprinted Polymer (MIP) were 12, 18, and 23 nm, respectively. The detection limit value (LOD) was 0.0981 μg/mL, and the quantitation limit value (LOQ) was 0.3273 μg/mL. At this limit of detection (LOD) no chloramphenicol was detected in the analyzed shrimp.
