Abstract

Azo dyes are complicated organic molecules which are often tough to degrade. They additionally might also produce greater unsafe intermediates for the duration of treatment processes. A novel catalytic approach to deal with these dyes is the need of time. However, there is a need to optimize the effective amount of catalyst and suitable pH to degrade pollutants and establish the rate of reactions or rate of degradation. It is crucial for the conversion of dye pollutants to non-harmful ones. This study has been carried out to study the kinetics of nickel and palladium catalysts using UV-visible spectrophotometer. This study is focused on the preparation of nickel and palladium catalysts to degrade Congo Red and Methyl Orange dyes. The catalysts were prepared by reaction of nickel nitrate hexahydrate (Ni (NO3)26H2O) and palladium chloride (PdCl2) with the support of tannin-chitosan. The results revealed that the optimized pH for nickel and palladium to degrade the dyes used was at pH 6. The catalytic activity showed that 80 mg of palladium and 60 mg of nickel have the highest degradation efficiency. From this study, it is revealed that the most efficient degradation occurred when palladium degraded methyl orange with the kinetic analysis of R2 equals to 0.9881 under optimized conditions.
