Fig. 5From: The influence of environmental conditions on kinetics of arsenite oxidation by manganese-oxidesEffect of As(III) concentration on manganese oxidation kinetics: the oxidation of arsenite by 1.82 mM δ-manganese-oxide (left) and acid birnessite (right). Concentrations of initial As(III) reacted include 100 μM, 1, and 10 mM at pH 7.2Back to article page
