The effect of humic acids on iron precipitation
- St. Vincent College, Latrobe, PA (United States)
Research involving the passive treatment of abandoned mine drainage and iron precipitation was conducted. The rate of iron precipitation from an alkaline mine drainage site in Latrobe, PA increases naturally whenever it comes in contact with Monastery Run, a stream in Latrobe, PA which is high in humic acids. To study the extent of humic acids` effect on the precipitation of metals from alkaline mine drainage, the rate of precipitation of iron, magnesium, manganese, and calcium was monitored after either Monastery Run water or Aldrich Humics were added to the alkaline mine drainage water. The rate of iron Precipitation did increase when Monastery Run water and Aldrich Humics were added to the alkaline mine drainage water. Different parameters which were studied along with the effect of humics on the precipitation of metals were concentration, ionic strength and alkalinity.
