Simultaneous analysis of chloramphenicol, amoxicillin, and enrofloxacin using electrochemical sensors with multilayer graphene electrodes fabricated by electrochemical methods in an organic solvent

Abstract

In this study, three antibiotics, chloramphenicol (CAP), amoxicillin (AMX), and enrofloxacin (ENR), were simultaneously analysed for the first time using electrochemical sensors. The multilayer graphene electrode used in the sensor was directly and rapidly fabricated from graphite through a onestep 
chronoamperometry method. Scanning electron microscopy and cyclic voltammetry techniques revealed the multilayer-graphene nanostructure of the prepared
electrode with a large electrochemically active surface area and good electrochemical activity...
