PHOTODEGRADATION OF PESTICIDES ON ADSORBED PHASES PHOTODEGRADATION OFCARBETAMID

The photochemical characteristics of carbetamid herbicide adsorbed on different solid supports were investigated. No significant difference was found for lambda max and triplet state of carbetamid, however, the structural properties such as specific area and reflection coefficien t are very different for each support. Silica was selected as the best support for the kinetic investigations of photodegradation of carbeta mid. A comparison with aqueous media was made and a mechanism of photo degradation of carbetamid was also proposed.
