Comparison of Activated Carbon from Water Bamboo Residues with Surfaces Modified by Different Methods


Article Preview

Surface modification of activated carbon was performed using such chemical methods as nitric acid and H2O2.Oxidation of the ACs made samples with weakly acidic functional groups and the presence of other groups was confirmed by Fourier transform infra red (FTIR) spectroscopy. With different time for modification, the amount of elements of carbon and oxygen will change a lot and the results of these experiments show a stronger ability of HNO3 solution in oxidization. Furthermore the differences of face morphology between ACs and oxidized ACs can be observed clearly
