Influence of Humic Substances on Photolysis of Nitroaromatic Compounds in Aqueous Systems

  title={Influence of Humic Substances on Photolysis of Nitroaromatic Compounds in Aqueous Systems},
  author={M S Simmons and Richard Zepp},
-Results are reported for kinetic studies of the photolysis of 19 nitroaromatic compounds in water. The results indicate that dissolved humic substances in natural waters enhance the sunlight-induced photodegradation rates of nitrobenzenes, nitrotoluenes, and nitroxylenes compared to rates observed in distilled water. The largest enhancements, ranging from 2 to 26-fold, were observed for nitroaromatics that are methylated ortho to the nitro group. Similar enhancement effects were observed for… CONTINUE READING
