Popis: | An optical multichannel apparatus was used to obtain Raman spectra from electrochemically oxidized pyrite in a neutral solution. The pyrite Raman spectra are compared with the spectra from electrochemically oxidized galena and sulfur electrodeposited on platinum. Elemental sulfur and polysulfides are found in the range 0.42–1.0 V vs. the saturated calomel electrode (SCE) for pyrite and 0.13–1.0 V(SCE) for galena. |
