AB  - Photocatalytic degradation of methyl red dye using Mn(5%) doped CdS nanoparticles was 
studied.Mn doped CdS nanoparticles was synthesized by microwave assisted solvo 
thermal method where the chemicals used wereCadmium Acetate [(CH<sub>3</sub>COO)<sub>2</sub>Cd, H<sub>2</sub>O], 
Manganese Chloride [MnCl<sub>2</sub>.2H<sub>2</sub>O] and Sodium Sulfide [Na<sub>2</sub>S.xH<sub>2</sub>O]. X-Ray 
diffraction(XRD) analysis was carried out in order to analyze the structural dimensions of 
the synthesized nanoparticles and the average crystallite size has been calculated at the full 
width half maximum (FWHM) of the diffraction peaks using Debye-Scherer equation and 
it was found to be around2.3nm. FTIR spectra analysis was done in order to analyze 
different functional and vibrational groups present in the as synthesized sample of Mn 
doped CdSnanoparticles.The morphology of sample wasstudied by scanning electron 
microscope. The aqueous solution of methyl red[C<sub>15</sub>H<sub>15</sub>N<sub>3</sub>O<sub>2</sub>] has been prepared and was 
mixed with the as synthesized Mn doped CdSnanoparticles and was exposed for 
photocatalytic degradation using 100 W bulb. UV-visible spectra of the light irradiated 
methyl red solutions were studied at different interval of time and no red shift was 
observed with increase of exposure time. The intensity of the absorption peak was also 
found to be reduced with the increasing time interval. The photo degradation of methyl red 
dye was observed up to 90% at the exposure time of 90 minutes.
