Electrochemical Investigation of Dicyclomine Hydrochloride at Poly (Terbutaline Sulphate) Modified Carbon Paste Electrode

Abstract

Dicyclomine Hydrochloride (DICY) has been studied on electropolymerisation of Terbutaline Sulphate (TBS) modified carbon paste electrode by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Voltammetric behavior of Dicyclomine Hydrochloride (DICY) on the poly (Terbutaline Sulphate) modified carbon paste electrode was investigated with electrochemical parameters of cyclic voltammetry. The variation of pH,Scan rate, Concentration of Dicyclomine Hydrochloride (DICY) has been studied. In optimal conditions, the oxidation peak current of DICY on the poly (Terbutaline Sulphate) modified carbon paste electrode was enhanced greatly indicating high sensitivity. The low detection limit (LOD) and low detection quantity (LOQ) of DICY has been found to be 0.12 M and 0.408 M with a correlation coefficient of 0.99461. The practical application of the modified electrode in the determination of DICY has good selectivity and high sensitivity.
