Abstract

The surface products of electrochemically oxidized pyrite (FeS₂) are investigated as a function of applied potential by using Raman spectroscopy. The parameters necessary for sulfur formation on the pyrite surface were determined. An optical multichannel apparatus, consisting of an argon laser, a triple spectrograph, and a charge-coupled-device detector, was utilized for the Raman measurements. The advantages of this system for surface characterization include high resolution and high sensitivity as well as the capability of identifying compounds and making in-situ measurements.
