Influences Of Acid Mine Drainage On Water Chemistry Of Blackwater River Watershed, Carla C. Morato-Lara
Theses, Dissertations and Capstones
Acidic mine drainage flow from active and abandoned coal mines has been a major source of water pollution in the Appalachian Mountain region of the eastern USA. Water samples were collected and analyzed from Blackwater River watershed during 2 years (September 1996 - May 1998). The water quality measurements determined that the Beaver Creek and North Fork tributaries were affected by acid mine drainage but not Yellow Creek. Beaver Creek and North Fork stations had high sulfate and manganese markers of acid mine drainage, whereas Yellow Creek was slightly acidic with low sulfate and manganese. North Fork was the primary …

Theses, Dissertations and Capstones
This study was concerned with the attempted development of a generalized synthesis of hexaphenylbutadiene. Three methods were attempted: Michael Addition of cyanide to -phenylcinnamate followed by organolithium or Grignard addition; reaction of benzil with two moles of the Wittig reagent prepared from bromodiphenylmethane; reaction of two moles of benzophenone with the bisphosphorane prepared from 1,2- dibromo-1,2-diphenylethane.
