【摘要】 进行了杨木硫酸盐浆氧脱木素的研究。研究了各影响因素（用碱量、温度和时间）对杨木硫酸盐浆氧脱木素的影响，确定了最佳条件。结果表明，杨木硫酸盐浆在适宜的条件下经氧脱木素，木素脱除率可达50％左右，白度提高约20个百分点，且粘度的损失不大。更多还原

【Abstract】 Oxygen delignification of populus kraft pu1p is studied. The results show that up to about 50%residual lignin in the pulp was removed under appropriate delignification conditions and pulp brightness exhibited about 20 percent increases with very little loss in viscosity. It was also found that the selectivity of oxygen delignification may be optimized with the appropriate combination of alkali charge, temperature and time.更多还原
