Photocatalytic degradation of Auramine O using BiOI/BiOCl/BiOPO4nanoparticles under blue light irradiationandmodeling by artificalneural networks

Dyes with complicated structure and their degradation products are highly toxic and carcinogenic. Auramine owas photodegradedunder blue light irradiation catalyzed byBiOI/BiOCl/BiOPO4.Neural network method is employed toestimate photocatalyticdegradation.To study this photo degradation, central composite design (CCD) under responsesurface methodology (RSM) was applied to design a systematic set of experiments. The CCD was used to investigate thesignificance of the effects of parameters including irradiation time, amount of photo catalyst and initial dye concentrationthat designed by using the DESIGN EXPORT 7. Variables such as initial dye concentration, photo catalyst dosage andirradiation time were involved in the experiments whilethe dye photo degradation percentage was considered as response.The effects of variables on the response were studied and optimized.
