Abstract
A heterogeneous Fenton-like process was studied using synthesised goethite (α-FeOOH) and hydrogen peroxide (H2O2) to degrade p-chloronitrobenzene (pCNB) in water. The effect on the treatment efficiency of the initial pH, the dosage of hydrogen peroxide and goethite and the presence of humic acid and bicarbonate were quantified. At the optimal conditions (pH=6.0, H2O2=6.6mg/L, and goethite=333mg/L), over 80% of pCNB was removed within 30min. Humic acid and bicarbonate were found to inhibit the pCNB degradation, probably because they compete with pCNB for theOH produced. Intermediate oxidation products were identified, and a pCNB oxidation pathway is proposed. The findings demonstrate that α-FeOOH combined with H2O2has potential as an advanced oxidation process for water pollution control.
