Design and study of a cost-effective solar photoreactor for pesticide removal from water

摘要

In order to remove pesticides from water, a basic photoreactor has been built. We evaluated thenperformance of this photoreactor using two commercial photocatalytic materials from Ahlstromngroup and from Saint-Gobain, with solar and artificial UV-lamps. We compared the kinetics ofnphotocatalytic degradation and mineralization of Diuron in the same reactor with of bothnphotocatalyst supports. We showed that Diuron is easily degraded under solar or artificialnirradiation, while the kinetics of mineralization in the same condition are very slow. Thenbehaviour of these commercial materials has been studied after several uses in the samenconditions. We showed the effectiveness of this basic and cheap photoreactor for the eliminationnof pesticide in water.
