SOLAR IRRADIANCE INDUCED PHOTOCATALYTIC DEGRADATION OF INDIGO CARMINE USING HYDROTHERMALLY DEVELOPED LITHIUM ZINCATE NANO POWDERS ASSESSED THROUGH ELECTRONIC SPECTRAL STUDIES. -

The ever increasing surface and ground water contaminations with industrial effluent discharges has necessitated the design and development of cost effective dye degradation strategies involving advanced oxidation process that take advantage of light induced degradation of dyes by utilizing semiconductor nano particles. Herein, Lithium Zincate (Li2ZnO2) nano particles with a crystal size of 20-40nm were developed through hydrothermal technique. The synthesized semiconductor was characterized by X-ray powder diffraction (XRD) method followed by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopic measurements. The photo catalytic degradation of Indigo carmine (IC) was affected using Li2ZnO2nano powder. The effect of parameters such as the catalyst load, dye concentration and irradiation time on photo catalytic degradation was established. - See more at:
