Abstract

In this paper, an electrochemical sensor was developed by Cyclic Voltammetric (CV) technique for the Determination of Anthrone (ANT) by using CTAB (Cetyl Trimetyl Ammonium Bromide) surfactant by immobilizing technique. The electrochemical behavior of ANT was studied at 0.2M PBS (6.5 pH) by CV technique. An enhanced current response has observed for Modified Carbon Paste Electrode (MCPE) towards ANT. Morphology of Bare Carbon Paste Electrode (BCPE) and MCPE were confirmed by Variable Pressure Scanning Electron Microscopy (VPSEM). The electrode process was adsorption controlled. Under optimum condition linear calibration plot of ANT was obtained from 3×10-5 M to 5×10-5 M and 6×10-5 M to 1.7×10-4 M with the detection limit of 21×10-7 M and limit of quantification of 7×10-6M. The modified electrochemical sensor was easy to fabricate, sensitive and having good stability.
