Water bodies had been polluted with contaminants discharged from industrial activities like dyes, pesticides and pharmaceutical in recent years. So, many alternatives had been used to treat the water contamination in water stream like activated carbon and adsorption methods. This research aim is to study the preparation and characterization of Nickel- Tannin/Chitosan by evaluating the catalytic activity effects on newly prepared catalyst. The catalyst was prepared by added Nickel Nitrate Hexahydrate, Ni(NO3)6H2O with Tannin-Chitosan support which form Nickel Tannin/Chitosan when undergoes several steps of reaction like hydrogenation process. The prepared Nickel Tannin/Chitosan was characterized using FTIR, XRD and SEM then used as catalyst in aqueous medium for oxidative degradation of 0.5M methylene blue. In this study, methylene blue acted as the pollutants to test the ability of Nickel Tannin/Chitosan as catalyst. Three different temperatures of 38°C,48°C and 58°C were conducted to test the percentage of dye degraded where time and concentration of methylene blue was observed in catalytic activity. From the results, about 74% of methylene blue degraded at 58°C with the presence of catalyst and hydrogen peroxide. This research showed Nickel Tannin/Chitosan has great ability as new catalyst which exhibit catalytic performance which can be used in the future especially for water treatment technology.
