In this work it was demonstrated the use of electrochemical techniques in the development of simple, low cost and portable analytical methods applied to Forensic Chemistry. The Square Wave Voltammetry (SWV) and Multiple Pulse Amperometry (MPA) techniques were used in association with the Batch Injection Analysis (BIA) system for cocaine determination and screening process of the most common adulterants (caffeine, phenacetin, benzocaine, lidocaine, procaine, paracetamol and levamisole) in seized samples, in addition to sibutramine and ephedrine in food supplements and herbal supplements. In the methods proposed in this work, the samples require only one step of dissolution in the supporting electrolyte prior to injection into the BIA cell. A...
