摘要：

The electrochemical oxidation of pyrite surfaces in near-neutral aqueous chloride solutions has been investigated using X-ray photoelectron spectroscopy (XPS), scanning electron microscopy/energy dispersive X-ray analysis (SEM/EDXA) and Raman spectroscopy in conjunction with electrochemical techniques. The surface oxidation products of pyrite, between 600 and 700 mV (SCE), have been identified by Raman spectroscopy as polysulphides and elemental sulphur. © 1990.
