| Abstract: | Lignin was modified with amines through Mannich reaction. The modification ratio of lignin was determined by see of acetate fiber membrane electrophoresis, which was linear with the nitrogen content of lignin amine, with correlation coefficient r = 0.9902.According to the F test, the linear relation was noticeable when α = 0.001.Experimental result proved it feasible to utilize eletrophoresis is to detemine the modification ratio, and this method was introduced. |

| Keywords: | lignin modification ratio membrane electrophoresis nitrogen content linear relation |
