摘要：

Activated carbons were prepared from bamboo by phosphoric acid activation. Samples were characterized by N-2 adsorption, Boehm titration, gas chromatograph-mass spectrometry, Fourier transform infrared spectroscopy and-scanning electron microscopy. The adsorption capacity, specific surface area, pore structure, surface functional groups and microstructure of the bamboo-based activated carbon were compared with those of coconut shell-based activated carbon prepared by steam activation Results showed that both activated carbons had almost similar acetate adsorption capacities, specific surface area and pore structure. Besides, the bamboo-based activated carbon had many more carboxyl, phenolic hydroxyl, P=O, P-O-C and P=OOH groups than the coconut shell-based activated carbon.
