OBJECTIVE To investigate reductive dechlorination of 4-chlorophenol (4-CP) by nanoscale Fe0 under different conditions. METHODS Nanoscale Fe0 was synthesized by using reductive method. 4-CP and its intermediate products were analyzed by HPLC. Chlorine ion was quantified with DX-100 ion chromatograph. Nano-iron particles were observed under a FEI Quanta 200 FEG environmental scanning electron ...

Background and purpose: Nitrobenzene (NB) as the main material of synthetic fuels, cleaners, rubber and explosives is discharged into the environment and groundwater in large-scale. This compound is considered as a persistent organic pollutant with high toxicity and stable chemical structure which can cause serious risks for human health and ecosystem even in low concentrations. Therefore, the ...
