Impact/Purpose:

information

Description:

The technology described in this report has been developed under the Emerging Technology Program of the Superfund Innovative Technology Evaluation (SITE) Program to photochemically oxidize organic compounds in wastewater by applying ultraviolet radiation using an excimer laser. The energy supplied by the laser is sufficient to stimulate photochemical reactions between the organics and hydrogen peroxide employed as a chemical oxidant, causing photooxidation and/or phototransformation of the toxic species to carbon dioxide, water and the corresponding halogenated acid. The photochemical reaction is capable of producing the complete destruction of low to moderate concentrations of toxic organics in water. ptimum conditions for the complete destruction of several different classes of compounds were developed and demonstrated in the laboratory.
