Figure 2From: Pyrite surface interaction with selected organic aqueous species under anoxic conditionsEffect of 0.1 mM Fe2+ (er-33), 0.5 mM Fe2+ (er-3) and O.1 mM Cu2+ (er-26) on the Ī¶-potential of a pyrite suspension kept under anoxic conditions. For reference, in experiment er-2 no metal was added. Starting ionic strength for each experiment was 5 mM, NaCl supported. For further parameters see Table 1.Back to article page
