Abstract
Present work describes the electrochemical sensing and determination of phenolic compound (Phloroglucinol) using non-ionic surfactant Octyl phenol ethoxylate modified carbon nanotube paste electrode (OPEMCNTPE) in PBS (0.1 mol, pH 6.0) by Voltammetric method. The developed electrode was characterized by field emission scanning electron microscope (FE-SEM) and cyclic voltammetric (CV) studies. The OPEMCNTPE shows an exceptional catalytic impact towards the electro-oxidation of Phloroglucinol (PL) in contrast to the bare carbon nanotube paste electrode (BCNTPE). The rise in the concentration of PL is directly proportional to PL anodic peak current in the linear working range 10–90 µmol with a small detection limit (LOD) 0.71 µmol. This method was utilized for the estimation of PL in the water and blood serum samples.
