BIOSORBENTS FOR REMOVAL OF CONTAMINANTS FROM WASTE/OIL SAND PROCESS-AFFECTED WATER (OSPW) AND CONSOLIDATION OF OIL SANDS TAILINGS

摘要

Methods of using modified keratin to remove trace metals and/or napthenicacids from awaste water stream are described. The waste water stream may be mature or finefluidtailings from oil sands operations, and the methods may include the removal oftrace metals,naphthenic acids with simultaneous consolidation of the tailings. The keratinmay bemodified to unfold the keratin, disrupt disulphide bonding, add functionalgroups, and/ormaintain or stabilize the unfolded configuration.
