Detecção de cobre empregando métodos voltamétricos e eletrodo de baixo custo.

Abstract

This work aims to implement a tool for the monitoring of water quality, preparation of a low cost electrode (using discarded cell) that was used in voltammetric techniques for the detection of copper in distilled / deionized water and fish tissue. The electrochemical analyzes were developed at LABMADE (Research Laboratory in Materials for Applications in Electronic Devices) located at the Federal University of Tocantins / Campus de Araguaína, using voltammetric techniques by means of a Potentiostat/ Galvanostat. The presence of high metal indices in water does not necessarily mean that there will be damage to living organisms, but they certainly indicate a state of latent contamination that could lead to toxicity. In this context, it is necessary to monitor the parameters of aquatic quality and of the beings that inhabit it.
