Electrochemical Determination of Chloramphenicol on Glassy Carbon Electrode Modified Activated Carbon Derived from Rice Husks

In the present article, application of activated carbon derived from rice husks (RHAC) with high surface area as an electrode modifier for electrochemical determination chloramphenicol (CP) is demonstrated. The RHAC was synthesized via a two-step alkaline pretreatment followed by ultrasound radiation. obtained materials were characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption/desorption isotherms, Fourier transformation Infrared (FT-IR) spectroscopy and Raman spectroscopy. It found that ultrasonic activation process plays critical role in improving textural properties AC removing fine particles to clean capillaries transforming graphitic structure turbostratic one. suitable conditions displayed specific up 1710 m 2 g −1 . glassy modified exhibited excellent electroactivity towards CP compared bare GCE. voltammetry characteristics sensor studied cyclic (CV) differential pulse (DPV). This had good performance linear response range 0.95–5.76 μ M low detection limit 0.66 (S/N = 3). promising selectivity, great stability expectable recovery real samples.
