摘要：

The photocatalytic reaction of xylidine ponceau on zinc oxide power was carried out. Photocatalytic bleaching of the dye was observed spectrophotometrically. The effects of the variation of various parameters, such as the concentration of xylidine ponceau, pH, amount and particle size of the semiconductor and light intensity, on the rate of photocatalytic bleaching were observed. A tentative mechanism for the photocatalytic bleaching of xylidine ponceau is proposed.
