Abstract
Present work reports the use of alumina nanoparticles catalyst for the photodegradation of congo red, methylene blue and methyl red dyes. These nanoparticles were prepared by reported method and were characterized by XRD, TEM and FTIR data. Alumina nanoparticles of average size 35 nm were then used for photodegradation of congo red, methylene blue and methyl red dyes. Alumina nanoparticles show a good photocatalytic activity toward degradation of congo red (94.39 %) dye and least toward degradation of methyl red (19.23 %). Kinetics of photodegradation of dyes catalyzed by alumina nanoparticles has been studied for 140 min. The data indicate that photodegradation process of congo red, methylene blue and methyl red followed a pseudo first order kinetics with rate constant values are 0.01929, 0.00420 and 0.00157, respectively and was monitored by UV-visible spectrophotometer.
