Surfactant modified electrochemical sensor for determination of Anthrone – A cyclic voltammetry
The two promising electrochemical sensor constructed using carbon paste electrode modified with Octyl phenol ethoxylate surfactant (OPEMCPE) and carbon paste electrode modified with Sodium lauryl sulfate (SLSMCPE). The electrochemical characterization of Anthrone (ANT) was studied at the surface of OPEMCPE with supporting electrolyte of pH 7.0 in 0.1 M phosphate buffer (PBS) and also at the surface of SLSMCPE with supporting electrolyte of pH 7.5 in 0.1 M PBS by using cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The OPEMCPE and SLSMCPE exhibited an efficient electrocatalytic activity towards ANT than the bare carbon paste electrode (BCPE). The characterization of both the electrodes are done by FE-SEM and EDX for SLSMCPE. The detection limit and limit of quantification of ANT employed in CV at the surface of OPEMCPE were 18.8 × 10−7 M and 6.27 × 10−6 M and at the surface of SLSMCPE were 10.6 × 10−7 M and 3.53 × 10−6 M. Moreover, tailored electrode offers high sensitivity, highly stable, good conductivity, transducing, biocompatibility, reliable to resistant electrode fouling and good reproducibility.
