摘　　要：对V_2O_5在NaOH-AQ麦草浆ClO2漂白中的助漂作用进行了研究,主要探讨了使其催化效果明显的影响因素。实验结果表明,V_2O_5是一种良好的漂白催化剂,具有降低氯酸盐的生成、提高ClO_2漂白能力的作用,当V_2O_5用量为0.14%,温度70℃,反应时间120 min.终点pH值4.0左右时,催化效果最为理想。In this paper, the application of vanadium pentoxide in chlorine dioxide bleaching of NaOH-AQ wheat straw pulp is reported. The results show that vanadium pentoxide can be used as the bleaching activating agent, which has advantages of both reducing chlorate formation and enhancing bleaching efficiency of chlorine dioxide. The optimal conditions for vanadium pentoxide involved chlorine dioxide bleaching are as follows： vanadium pentoxide dosage 0.14%, temperature 70℃, time 120 min, and final pH4.0.
