| Abstract: | The optimum pretreating condition for SCMP (sulphonated chemi mechanical pulp) is studied in this paper.The result shows that brightness and strength of pulp pretreated with DTPA/Na 2SO 3 before bleaching are increased,and yellowing value of pulp is decreased,content of metal ion reduced obviously. |
