  desorption kinetics of trace contaminants on S -PAC when in competition with a strongly competing compound and (ii) measuring the desorption kinetics of trace contaminants on S-PAC when in competition with a strongly competing compound and a pore blocking organic compound. A bituminous coal based activated carbon, WC800, and a wood based activated. Removal of Trace Metals from Acid Mine Drainage Using a  · Potentially scalable low-cost treatment methods for acid mine drainage (AMD) are very limited. We used a sequential combination of adsorption and phytoremediation by bunchgrass (Vetiver [Vetiveria zizanioides L]) in a semi-batch system to remove Zn, Mn, Ni, and Cu from AMD. The objectives were: (1) to compare the removal of these metals by raw and
