Influence of the surface speciation on biofilm attachment to chalcopyrite by Acidithiobacillus thiooxidans

Abstract

Surfaces of massive chalcopyrite (CuFeS2) electrodes were modified by applying variable oxidation potential pulses under growth media in order to induce the formation of different secondary phases (e.g., copper-rich polysulfides, S n 2−; elemental sulfur, S0; and covellite, CuS). The evolution of reactivity (oxidation capacity) of the resulting chalcopyrite… (More)
