Figure 3From: Pyrite surface interaction with selected organic aqueous species under anoxic conditionsInteraction of acetate and alanine with pyrite. (a) Aqueous speciation distribution as a function of pH. (b) Curves er-37 (no added Fe2+) and er-24 [0.5 mM Fe(NH4)(SO4)2] were measured in 0.5 mM acetate suspensions, whereas curves er-38 (no added Fe2+) and er-29 [0.5 mM Fe(NH4)(SO4)2] were obtained measuring 0.5 mM alanine suspensions.Back to article page
