Abstract

This experimental study was conducted to investigate the COD and color removal efficiency in printing and dyeing wastewater by ferrate and by UV irradiation combined with the ferrate pre-oxidization. The experiment results showed that 77.5% COD and 76.6% color removal efficiency could be attained at pH 5 with 77.0 mgldrL^-1 ferrate (in terms of Fe(VI) ions). After the oxidation by 77.0 mgldrL^-1 ferrate at pH 3, the COD and color removal efficiency was 69% and 87.5%, respectively. However, the irradiation had no obvious effect on COD and color removal efficiency after ferrate pre-oxidation.
