TI  - Electroanalytical Analysis of Guaifenesin from Pharmaceuticals on Boron Doped Diamond Electrode
AB  - Electrochemical analysis of the expectorant drug guaifenesin was performed on boron doped diamond electrode by cyclic voltammetry, differential pulse voltammetry, and square wave voltammetry techniques. The results of cyclic voltammetry studies indicated that the reaction mechanism of guaifenesin in the anodic direction was irreversible, and diffusion controlled. The linearity ranges of the peak currents versus guaifenesin concentration were between 0.4 and 100 μM with a detection limit of 1.47 nM for differential pulse voltammetry and between 0.8 and 100 μM with a detection limit of 2.92 nM for square wave voltammetry. Quantitative analysis of guaifenesin from the pharmaceuticals was performed using the proposed methods without any pre-separation. Sensitive voltammetric methods with good recovery, high sensitivity and accuracy were developed for the electroanalytical analysis of guaifenesin.
