| Abstract: | The optimum synthesis conditions of lignin modification by quaternary ammonium salt were described. Through orthogonal tests the best conditions obtained were as follows： activating time 3min, reaction temperature 70℃, feed ratio of lignin to quaternary ammonium salt 1 ：2. 5, and stirring speed 600 r/min. FT - IR spectra verified the success of lignin modification. The flocculation performance of modified lignin was compared with that of lignin by treatment of printing waste water. |
