Exhaustive Removal of the Aqueous Phase Component

Essentially complete removal of water soluble phenol (sodium phenolate) and cyanide (sodium cyanide) has been achieved. We presented data at the August 2002 American Chemical Society meeting in Boston that showed over 99.9% removal of these two materials in one to two hours from batch systems containing starting concentrations of 1 wt% in water at 50°C. Thus an aqueous stream containing these or other water soluble anions can be stripped of its most offending chemical and can make the stream acceptable to waste treatment. This is why we call it Value Recovery. (See Articles Section for journal reference.)
