Descripción
Waste of electrical and electronic equipment is an interesting secondary resource of base and precious metals. Par- ticularly the use of thiourea-leaching in acidic medium was proposed for noble metals recovery. In this work, a novel and easy-to-use electrochemical sensor was developed, aimed to test thiourea from leaching solutions con- taining significant thiourea and copper amounts. The sensor was constructed using silver nanoparticles (AgNPs) de- posited on screen-printed electrodes. Its performance was studied in a synthetic leaching solution; changes in the overall surface charge of AgNPs resulting in changes in the charge-transfer resistance for the copper ions were eval- uated by electrochemical impedance spectroscopy.
