The use of petroleum coke was proposed as a potential adsorbent for organic contaminant removal from tailings pond water. Physical activation was used to create a greater surface area and porosity within the delayed and fluid coke. Increased temperature (900oC), steam rate (0.5 mL/min), and activated time (6 h) led to high iodine numbers of 670 and 620 mg/g for activated delayed and fluid cokes, respectively. For both best activated cokes, the micropore to mesopore ratio was approximately 50:50. When 5 g/L of activated delayed and fluid cokes were added to the tailings water, 91% of the dissolved organic carbon and 92% of the naphthenic acids were removed. Such analyses indicate that an oil sands waste by-product can be used to treat tailings pond water to remove toxic and corrosive organic contaminants. </style></abstract><custom2><style face="normal" font="default" size="100%">Alberta oil sands</style></custom2><custom3><style face="normal" font="default" size="100%">http://www.worldcat.org/oclc/697531620</style></custom3><custom4><style face="normal" font="default" size="100%">OSEMB</style></custom4></record></records></xml>
