Pharmaceuticallyactive compounds are gaining the recognition of emerging environmentalcontaminants classified as recalcitrant bio-accumulative compounds hence they are regardedas toxic and hazardous chemicals. In this context, efficient treatmentprocesses are needed. Nanotechnology can adequately address many of the waterquality issues by using different types nanomaterials. Nano zero valent iron(nZVI) has been appliedto remove various organic compounds from aqueous solutions since the removalmechanism depends on adsorption and degradation. This article summarizes the recent knowledge of nZVIin pharmaceutical degradation considering the key factors such as initialcontaminant concentration, dosage of bare and modified nZVI, pH of aqueous matrix and reaction time which are mainly examined inthe experiments. Additionally, the degradation mechanism of studiedpharmaceutical compounds monitored by observing intermediates and end-productsis presented.
