Abstract

Un dispositivo para medir los niveles de pH y la concentración de contaminantes incluye un montaje de electrodos que está acoplado eléctricamente a una unidad de control; el montaje de electrodos incluye un primer contacto acoplado eléctricamente a un electrodo de referencia, un segundo contacto acoplado eléctricamente a un electrodo de trabajo y un tercer contacto acoplado eléctricamente a un contraelectrodo; el electrodo de trabajo puede ser modificado para incluir un óxido de grafeno funcionalizado con cisteína con nanocompuesto de polipirrol; en funcionamiento, la unidad de control puede aplicar una señal compleja al electrodo de trabajo a través del segundo contacto para adherirse y posteriormente eliminar los iones contaminantes de la muestra de fluido al electrodo de trabajo; durante este procedimiento, se puede medir una corriente a través del electrodo de referencia y del contraelectrodo para medir la concentración de iones contaminantes; el pH de la muestra de fluido también puede determinarse mediante una corriente medida a través del electrodo de referencia y del contraelectrodo; en algunos ejemplos, el pH puede usarse para calibrar los niveles medidos de los iones contaminantes.
