Nullifying nitrophenols

A chemical catalyst developed at

completely destroys dangerous nitrophenols in laboratory tests, according to Arani Chanda, a doctoral student who recently presented his findings at the 230th meeting of the

(ACS) in

.

"We found an efficient, rapid and environmentally friendly means of completely destroying these compounds," said Chanda, who works in the laboratory of Terrence Collins, the Thomas Lord Professor of Chemistry and director of the Institute for Green Oxidation Chemistry at the Mellon College of Science (MCS) at Carnegie Mellon.

Nitrophenols are man-made pollutants that mostly originate from wastewater discharges from the dye, pesticide and ammunition industries as well as from various chemical-manufacturing plants. They are also found in diesel exhaust particles. Thousands of tons of these agents are produced yearly by countries around the world.

Registered as priority pollutants by the US Environmental Protection Agency (EPA), they are toxic to aquatic life. They produce immediate toxic effects to the nervous system, and some reports have implicated them as possible endocrine disruptors. Many of these compounds cannot be destroyed by existing means.
