A novel composition is formed by suspending a carbonaceous adsorbent in a branched hydrocarbon solvent. In addition, said powdered carbonaceous adsorbent suspended in a hydrocarbon solvent, preferably a branched hydrocarbon solvent, is an effective adsorbent-extractant for removing both soluble and insoluble organic materials from waste water. Use of this suspension as an adsorbent enables the use of a continuous adsorption process having high capacity for removal of contaminants, fast contaminant removal rates and high adsorbent utilization while permitting easy staged contacting. The spent suspension may then be regenerated by vapor stripping or solvent extraction. |
