ABSTRACT


In the present study Zinc oxide (ZnO) was doped with activated carbon prepared from the plant material by chemical activation namely, Vitex negundo carbon (VNC). Dyes are usually present in trace quantities in the treated effluents of many industries. Zinc oxide (ZnO) was used in the photocatalytic decolourisation and degradation study of a dye namely, methylene blue (MB) and malachite green (MG). The carried out to find out the efficiency of photocatalytic property of ZnO / VNC. The reaction was performed at 20 ppm solute ZnO / VNC ion at 10 min interval of time. It found that the prepared ZnO / VNC composite exhibits an enhanced photocatalytic activity for MB degradation under visible light irradiation and its photo catalysis efficiency was analyzed in specific 663.88 nm λmax using a UV–vis-spectrophotometer. MG degradation under visible light irradiation 615.59 nm λmax. The potential of ZnO / VNC material was used as an alternative low cost adsorbent for the removal of MB and MG from aqueoussolution.


Keywords: ZnO / VNC, Methylene Blue (MB), Malachite Green (MG), H2SO4
