Elevated nitrate concentrations in groundwater and surface water supplies can negatively impact the quality of environment human health. Recent studies have examined use zero-valent iron technology to treat nitrate-contaminated groundwater. Mechanistic aspects reduction by are unresolved. This project investigated kinetics mechanism under anoxic conditions oxic conditions. Stirred-batch reactio...

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...
