摘要：
In this work, the variation of hexenuronic acid (HexA) during chlorine dioxide bleaching of bagasse pulp was studied under different reaction times and chlorine dioxide dosage. The results revealed that there is a linear relationship between the HexA content and the natural logarithm of the reaction time and the amount of chlorine dioxide. An empirical model was established: C-HexA = -0.901 x Ln (t - 2.74) - 131.7C + 13.036 (R-2 = 0.9419). It can provide a reference for the analysis and control of HexA residual in the chlorine dioxide bleaching of bagasse pulp.
