以竹节为原料，采用磷酸法制备醋酸乙烯催化剂载体活性炭。采用N2吸附等温线、Boehm滴定法、热重-质谱仪( TG-MS)、傅里叶红外光谱仪( FT-IR)和扫描电子显微镜( SEM)，对磷酸法竹活性炭和水蒸气法椰壳活性炭的吸附性能、比表面积、孔结构、表面官能团和微观结构进行比较。结果表明，竹活性炭的醋酸吸附性能、比表面积和孔隙结构与椰壳活性炭相近；且竹活性炭具有更丰富的-COO-、-OH-和 P=O 、P-O-C和 P=OOH 等表面官能团。磷酸法竹活性炭的制备有望为醋酸乙烯催化剂载体活性炭的生产提供新工艺，实现对水蒸气法制备椰壳活性炭的替代。

Activated carbons were prepared from bamboo by phosphoric acid activation. Samples were characterized by N2 ad-sorption, Boehm titration, gas chromatograph-mass spectrometry, Fourier transform infrared spectroscopy and scanning electron mi-croscopy. 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.
