Determination of clenbuterol with differential pulse anodic stripping voltammetry technique at tungsten disulfide-modified electrode

In the present work, tungsten disulfide was synthesised and characterised by using X-ray diffraction and scanning electron microscopy. This material was employed to modify a glassy-carbon electrode to analyse clenbuterol. The results show that tungsten disulfide displays electrocatalytic activity toward clenbuterol oxidation. The proposed technique is prospective for clenbuterol examination. The limit of detection and the linear range are 0.51 mM and 1–210 mM.
