Destruction of pesticides and their formulations in water using short wavelength UV light
- Univ. of California, Davis (USA)
The presence of toxic materials in surface and ground water is a problem of growing significance. Increasingly, toxic anthropogenic chemicals are being detected in water supplies resulting in public concern and regulatory restrictions. Clearly, there is a need to develop methods to decontaminate not only drinking water supplies, but also the sources of contamination. Decontamination of water poses economic and logistical challenges since the pollutants are usually present in low concentrations and distributed over a wide area. A number of strategies have been proposed and tested to destroy toxic materials in water. In this study, the authors examined the effectiveness of a photoreactor equipped with a high pressure mercury vapor lamp for the destruction of three pesticides and the inert ingredient m-xylene in water. Captan, chlordane, PCNB, and m-xylene in aqueous solutions were selected as model compounds for this study based on their use, resistance to UV degradation, and potential presence in formulated pesticide materials. The factors that influence the performance of the system were investigated.
