Effects of iron on arsenic speciation and redox chemistry

1. Introduction. Because of a rich history of mining, acid mine drainage (AMD) is a common problem in areas of the Western United States. Oxidation of pyritic ores is a major cause of acidic drainage (Wildeman et al., 1974, Black and Craw, 2001, Gault et al., 2001).The production of iron(III) and hydrogen ions can catalytically dissolve secondary minerals, thereby increasing the metal load to
