The study was conducted to understand, (a) the effect of pH on the speciation of uranium in acid mine drainage and (b) determine the effect of uranium speciation on the removal of gross alpha activity from acid mine drainage. Speciation modeling predicted a dominance of neutral and positively charged species under acidic and neutral conditions. Negative species become dominant from pH 8. The effectiveness of the anionic exchange resin to remove gross alpha activity was lower under acidic conditions (pH < 6) compared to alkaline conditions (pH ≥ 8).
