Fe-TAML(R) activators developed at Carnegie Mellon decolorize textile mill wastewater

f dye removed from effluent, according to Horwitz, who added that employing Fe-TAML activators could enable manufacturers to recycle water used in textile dyeing. This step would reduce overall plant costs and save millions of gallons of water yearly over the entire industry. Theoretically, sunlight would also penetrate Fe-TAML-treated water much more easily than dyed water, thereby improving the survival of aquatic fish and plants.

Fe-TAML activators originated at Carnegie Mellons Institute for Green Oxidation Chemistry under the leadership of Terry Collins, the Thomas Lord Professor of Chemistry at the Mellon College of Science. Collins is a strong proponent of green chemistry to create environmentally friendly, sustainable technologies. Fe-TAML activators show enormous potential to provide clean, safe alternatives to existing industrial practices. They also provide ways to remediate other pressing problems that currently lack solutions. The dye decolorization research was supported in part by the Eden Hall Foundation of Pittsburgh.

As part of this Septembers American Chemical Society meeting symposium, "Green Chemistry: Multidisciplinary Science and Engineering Applied to Global Environmental Issues," the Collins' group will present results of Fe-TAML activators' effectiveness in killing a simulant of a biological warfare agent, reducing fuel pollutants, treating pulp and paper processing byproducts, and de-toxifying pesticides. At the symposium, the Collins group also will highlight how Fe-TAML activators can work with oxygen rather than hydrogen peroxide, thereby extending tremendously the range of potential applications of these catalysts.
