Pharmaceutically
active compounds are gaining the recognition of emerging environmental
contaminants classified as recalcitrant bio-accumulative compounds hence they are regarded
as toxic and hazardous chemicals. In this context, efficient treatment
processes are needed. Nanotechnology can adequately address many of the water
quality issues by using different types nanomaterials. Nano zero valent iron
(nZVI) has been applied
to remove various organic compounds from aqueous solutions since the removal
mechanism depends on adsorption and degradation. This article summarizes the recent knowledge of nZVI
in pharmaceutical degradation considering the key factors such as initial
contaminant concentration, dosage of bare and modified nZVI, pH of aqueous matrix and reaction time which are mainly examined in
the experiments. Additionally, the degradation mechanism of studied
pharmaceutical compounds monitored by observing intermediates and end-products
is presented.
