Initial pH of each solution was adjusted to 3.0 with HCl and NaOH. In OA’s absence, nZVI reactivity was realised to be relatively low (as illustrated in Fig. 1a). Degradation efficiency of NB by nZVI under various aerations was in the following order: O2 (35%) > N2 (29%) > without aeration (10%). This sequence had also been discerned in earlier studies [10], [11]. It was reported that the reduction species (H) was significant in the pollutants degradation under anoxic conditions [9]. Different from

Being that the influence of organic ligands on contaminant removal by nanoscale zero valent iron (nZVI) has been explored in quite a few studies, there is little information on reaction mechanisms of the ZVI-ligand system under different aeration conditions. The degradation of nitrobenzene (NB) by nZVI-oxalic acids (OA) was investigated under N2, O2 and without aeration conditions. From the findings, it was evident that OA dramatically improved NB degradation by nZVI with all of the aeration conditions. Approximately 100% of NB was degraded by ...
