Synthesis of CoFe۲O۴@Zn-MOF nanocomposite-graphene nanoflake nanocomposite for effective degradation using experimental design

In recent years, one of the growing environmental concerns has been the contamination of water sources by dyes. For solving this problem, different nanostructures with various potentials have been suggested. In this work, a new nanostructure of CoFe۲O۴@Zn-MOF-graphene nanoflake was synthesized. This nanostructure was developed for photocatalytic degradation of diazinon from an aqueous solution. Further, ۲k-۱ factorial design was used for investigating the effect of various experimental parameters including catalyst dosage, contact time, initial dye concentration, and pH on the photocatalyst behaviors of CoFe۲O۴@Zn-MOF-graphene nanoflake. The results of the analysis of variance confirmed that these parameters have a significant effect on the degradation efficiency of diazinon by CoFe۲O۴@Zn-MOF-graphene nanoflake. For achieving the best optimization of the BG degradation, the response surface methodology was applied. According to this methodology, the CoFe۲O۴@Zn-MOF-graphene nanoflake has a significant potential for diazinon degradation as high as ۹۹%.
