Abstract :
In search of remedy to water pollution, a new nanomaterial Pb2Cd4Sr2O10 is synthesized by co-precipitation method and calcined. It is then characterized by various analytical methods like Fe-SEM, XRD, XPS, EDX etc. Band gap of the material is calculated to be 5.6 eV. This is then used for degradation of Erythrosine B in solar light and is observed to degrade it up to 98% in 60 minutes of exposure. Study suggests that reaction follows pseudo first order kinetic law. Maximum degradation conditions are extracted by varying the affecting factors and the rate constant obtained is 4.007 x 10-4 sec−1. Scavenger study suggests participation of •OH free radicals. Recycling experiment states that the photocatalyst can be used again up to five cycles without any loss in its efficiency. End products are ascertained by laboratory tests. A mechanism is also proposed.
