conference contribution

The catalysts are synthesised by hydrothermal reaction of ball-milled phosphating slag with ammonia, ethanol, and oxalic acid respectively. The catalysts are characterized by XRD, SEM and UV-Vis absorption spectra. We studied the photocatalytic degradation efficiency of different catalysts and the amount of catalysts on the organic dye rhodamine B and methyl orange. The results shows that the catalyst prepared by the hydrothermal reaction of 1 mol/L oxalic acid with phosphating slag has a microporous structure after being modified by high temperature, the degradation efficiency of rhodamine B and methyl orange which are carried out for 120 min under the irradiation of 100 w mercury lamp can reach 78% and 81%, and the optimal amount of catalyst is 0.5 g/L. This study provides a new solution for the utilization of phosphating slag.
