Photocatalytic degradation efficiency of malachite green in aqueous medium using poly(azomethine)/ZnO nanocomposite

The photocatalytic efficiency of the poly(azomethine)/zinc oxide (PNZ) nanocomposites was evaluated for the removal of toxic effluent, Malachite green in the presence of natural sunlight. The photocatalytic efficiency of the PNZ was explored with different parameters and reaction conditions. From the photocatalytic experiments, the deprivation efficiency wasevaluated which reveals that the PNZ nanocomposites exhibited excellent photocatalytic activity than the polymer, poly(azomethine) (PAZ), and nanoZnO (ZnO). The PNZ nanocomposite showed maximum degradation efficiency of 95 % at optimum catalyst dosage (500 mg) with low dye concentration. The main aim of this research was to protect our environment from the contamination of effluence released from dyestuff industries using effective nanocomposite.
