【Abstract】 We investigate the bleaching of neutral sulfite reed pulp by peroxy acetic acid (PAC). Experiment result shows that bleaching temperature is the primary effecting factor, pH and the charge of PAC are the next. In the range from 30?min to 60?min the time of bleaching exerts nearly no effect. The proper conditions of bleaching are:temperature, 80?℃; charge of PAC, 2%(on od. pulp); pH,6.0;time, 30?min.更多还原
