Sunlight Photocatalytic of dazomet herbicides in aqueous solution


The solar photocatalytic of an aqueous dazomet were carried out under natural weathering conditions. Photocatalytic of 50 μg/ml dazomet solution degraded 93.5. % of the solution after one hour of solar irradiation, by using 40 mg of zinc oxide as a catalyst . The effect of various parameters such as amount of catalyst and illumination time on the degradation of dazomet has been studied The degradation percentages were investigated by monitoring the dazomet mineralization spectrophotometrically. The mineralization rate of dazomet is calculate.
