摘要
The structure of three kinds of milled wood lignin and its chemical products was studied by FTIR and XPS. The binding energy of C-1s was assigned to 283.52 (C-H or C-Q, 284.58 similar to 285.72 (C-OR or C-OH), 286.10 similar to 286.44 (C=O or HO-C-OR), 287.65 similar to 287.72 (O-C=O) eV and O-1s binding energy was to 530.31 (O-H), 531.45 similar to 531.72 (RC=O), 532.73 similar to 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.
