| 抄録 | It has been found that activated carbon oxidized with a solution prepared by dissolving (NH4)2S2O8 in 1.0 M sulfuric acid has a very large number of functional groups and increases the adsorption of metal ions. However, the oxidation simultaneously produces a decrease in surface area and causes the activated carbon to have a fragile structure. This study examined the effects of nitric acid, sodium sulfate and sulfuric acid as (NH4)2S2O8 solvents used for the oxidation of activated carbons on Ni(II) adsorption, oxygen content, functional groups and surface area. The results showed that 1.0 M solvents introduce more carboxy groups than 0.1 M solvents and a 1.0 M sodium sulfate solution produces a high adsorption capacity without decreasing the surface area drastically. |
