The treatment of waste water involves, amongst other processes, the removal of heavy metal ion pollutants and/or organic contaminants. As one component of a potential aluminosilicate nanocomposite for water treatment, we have demonstrated the effectiveness of using Maghemite (γ-Fe2O 3) as a photocatalyst for the reduction of the aqueous pollutant chromium(VI) to chromium(III) in the presence of a sacrificial organic reductant. Maghemite has the twin advantages of being a photocatalyst that exhibits strong absorbance in the visible region of the spectrum and of being magnetic, so facilitating post processing solid/liquid separation. During this study, a simple, robust, calibrationless potentiometric technique for monitoring the concentration of chromium(VI) was developed. This method allowed the photocatalytic reduction of Cr(VI) to be observed in real-time with no sample pre-treatment.
