Evaluation of the Electrochemical Behavior of Carbon Paste Electrode (CPE) with Chalcopyrite (CuFeS₂) in the Presence of Ferrous Ions

Abstract:

In this work we present an electrochemical study using carbon paste electrode (CPE) with CuFeS₂ in solutions with different concentrations of Fe²⁺ ions in order to evaluate the possible interaction between these ions and mineral sulfide in the absence and presence of the bacteria Acidithiobacillus ferroxidans.
