Oil sands coke is a promising adsorbent for removing dissolved organic carbon (DO C), which includes toxic acid-extractableoil sands tailings organics (AEOSTO) found in PA water. The ability of raw and activated delayed and fluid coke to remove DOC andAEOSTO from PA water was assessed. Treatment with 5 g∕L of activated delayed and fluid coke removed 91% of DOC and 92% ofAEOSTO at levels of 36 mg∕L and 60 mg∕L, respectively. Heavy metal leaching of vanadium at 5:9mg∕L was observed for a 5 g∕Lapplication of activated delayed coke, representing a challenge to the approach. Microtox testing indicated that higher carbon doses ofactivated cokes were effective in reducing toxic the biological response caused by organic compounds; however, exposure to heavy metalsincreased the toxic effect with time. The propos ed methodology should be coupled with an inorganic treatment technique for complete oilsands tailings water treatment. </style></abstract><issue><style face="normal" font="default" size="100%">8</style></issue><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/847653996</style></custom3><custom4><style face="normal" font="default" size="100%">OSEMB</style></custom4></record></records></xml>
