Abstract

This research was conducted to study changes in functional groups of porous carbon synthesized from mlanding or petai sawdust after being oxidized with H2O2 at various temperatures i.e. 30°C, 60°C, and 80°C. In addition, the effect of porous carbon after oxidation for nickel ion adsorption was also investigated. Adsorption experiments were carried out using solution of Hexammine Nickel (II) Nitrate [Ni(NH3)6](NO3)2 synthesized by adding Nickel (II) Nitrat Heksahidrat to Ammonia solution The carbon inside nickel solution was shaken for 48 hours using a water bath shaker at a temperature variation of 30°C, 40°C, and 60°C. The results of this study indicate that the oxidation of porous carbon will increase functional groups concentration on the surface of carbon such as lactone, carboxyl, and phenol.Adsorption isotherm of nickel ions by porous carbon from mlanding wood follows the Langmuir isotherm plot and shows better performance for absorbing nickel ions in solution compared to carbon without oxidized.
