ZNO nanoparticles as a model for removal of pharmaceutical compounds (Vitamin B12)in the presence of UVA light

Abstract

The photocatalytic degradation of an aqueous solution of Vitamin B12 drug has studied under different conditions in the presence of ZnO nanoparticles suspension. The effect of various parameters such as mass of ZnO, Vitamin B12 drug concentration and study Removal of a real sample (mixture of pharmaceuticals compounds) by using ZnO. Results showed that, the photo catalytic degradation process was high at the beginning and then decreased with time. The explained the photo catalytic degradation efficiency, which was increased by increasing catalyst loading from 0.05 to 0.2 g. The degradation efficiency decreased with the increase in catalyst loading. Results also showed that the rate of photo catalytic degradation was increased with decreasing Vitamin B12 drug concentration.
