Highly sensitive voltammetric determination of hydrochlorothiazide using a glassy carbon electrode modified with Super P carbon black nanoparticles.

Hydrochlorothiazide is an extremely important diuretic that regulates body functions, which can prevent several diseases. However, the abuse of this diuretic is concerning since it does not require a medical prescription, particularly for aesthetic purposes such as weight loss, which can lead to various health problems, including ventricular arrhythmia. The present work aims to use a glassy carbon electrode modified with Super P carbon black (SPCB/GCE) to quantify hydrochlorothiazide through Linear Sweep Adsorptive Stripping Voltammetry (LSAdSV).
