Fluoroquinolone antibiotics attract increasing attention in the water treatment field because of potential adverse effects on aquatic ecosystems and human health. The graphitic carbon nitride (g-C 3 N 4 ) based photocatalysis has been demonstrated as an economically feasible environmentally benign process to control these persistent contaminants. In this study, a new visible-light-driven reduce...

In this study, two different mixtures of municipal compost, limestone and zero-valent iron were assessed in two column experiments on acid rock treatment. The effluent solution was systematically analysed throughout the experiments and precipitates from both columns were withdrawn for scanning electron microscopy, energy-dispersive X-ray spectroscopy and X-ray diffractometry were analyzed. Resu...

Reactions involving iron play a major role in the environmental cycling of a wide range of important organic, inorganic and radioactive contaminants. Consequently, a range of environmental clean-up technologies have been proposed or developed which utilise iron chemistry to remediate contaminated land and surface and subsurface waters, e.g. the use of injected zero zero-valent iron nanoparticle...

Based on ultrasonic cavitation, with low concentration of levofloxacin hydrochloride solution and cavitation product analysis, the degradation rules were studied by ultrasonic, zero valent iron valence (US / Fe0). The results showed that zero-valent promotes reaction fits first-order kinetic model, a rate constant 6.3710-3min-1. Under conditions, biodegradability was significantly improved, aft...
