Sandeep Ramesh Gadhave | Jayshree Parikh | Haribhau Ramrao Aher

Abstract: Green synthesized zinc oxide nanoparticles and its application in degradation of malachite green dye. Degradation carried out in presence and absence of zinc oxide nanoparticles as catalyst in dark condition, resulting with degradation efficiency of 4.11 % without catalyst and 19.02 % in presence of catalyst. Photocatalytic degradation of malachite green dye was carried out through various parameters, as comparative study was conducted in presence of sunlight for zinc oxide nanoparticles, precursor salt, leaves extract of Michelia Champaka plant. Comparative study for degradation of malachite green dye results as, degradation conducted in presence of zinc oxide nanoparticle as catalyst degrades 83.06% of dye, zinc nitrate salt degrades 17.33% of dye, Leaves extract of Michelia Champaka degrades 74.16% of dye and malachite green dye self - degradation in sunlight is 4.74%. Degradation study was carried for 180minutes to attain maximum degradation of dye.
