he structure of three kinds of milled wood lignin and its chemical products was studied by FTIR and XPS. The binding energy of C1s was assigned to 283.52 (C—H or C—C), 284.58～285.72 (C—OR or C—OH), 286.10～286.44 (C＝O or HO—C—OR), 287.65～287.72 (O—C＝O) eV and O1s binding energy was to 530.31 (O—H), 531.45～531.72 (RC＝O), 532.73～533.74 (O—C＝O) eV respectively. Bamboo lignin was bound mainly through ester linkage and C—C bonds. The proportion of ether, C—C bond, ester, carbonyl and unsaturated double bonds is 100∶63∶32∶40∶32 (49.3∶31.0∶16.0∶19.9∶16.0) correspondingly.
