Abstract: The influence of nitric acid modification on the ash, pH, surface element content and structure of the activated carbon was studied. The result indicates that the nitric acid modification of activated carbon can reduce the ash content, pH, specific surface area of the activated carbon,but increase the surface oxygen content of activated carbon.

Key words: activated carbon, nitro acid, modification
