ENHANCED IMMOBILIZATION OF ARSENIC FROM ACID MINE DRAINAGE BY DETRITAL CLAY MINERALS
Lefticariu, L., S.R. Sutton, A. Lanzirotti, and T.M. Flynn.
ACS Earth and Space Chemistry 3(11):2525-2538(2019)
Detrital clay minerals that originated from the partial weathering of coal mining waste increased total As uptake in acid mine drainage sediments. Clays controlled As mobility during sustained redox cycling by (1) enhancing heterogeneous precipitation of Fe(III) precipitates (Fe(III)NP) under oxic conditions which adsorbed or incorporated As and (2) facilitating the transfer of As from Fe(III)NP to clay during microbially-mediated reduction of Fe(III)NP coatings under anoxic conditions.
