XPS STUDY OF REDUCTIVE DISSOLUTION OF 7#9-BIRNESSITE BY H3ASO3, WITH CONSTRAINTS ON REACTION MECHANISM - PART 1. EXAFS STTUDIES OF THE GEOMETRY OF COPRECIPITATED AND ADSORBED ARSENATE

Nesbitt H.W.; Canning G.W.; Bancroft G.M. (1998)

Reductive dissolution of synthetic birnessite (MnO1.7(OH)0.25 or MnO1.95) by arsenious acid (H3AsO3) proceeds in two steps. The first entails reduction of Mn(IV) to Mn(III), with stoichiometry: 2MnO2+H3AsO3=2MnOOH*+H3AsO4H3AsO3 ...
