摘　　要：以硫酸盐竹浆为原料、过硫酸氢钾复合盐为漂白剂,进行硫酸盐竹浆的漂白试验,研究过硫酸氢钾复合盐对硫酸盐竹浆的漂白作用。结果表明:过硫酸氢钾复合盐对氧脱木素后的浆料有明显的漂白作用,可氧化脱除纸浆中的残余木素,使浆料的卡伯值降低、白度提高;其适宜的漂白条件为:纸浆浓度10%、漂剂用量1.2%、pH 10.5、温度60℃、时间60 min;过硫酸氢钾复合盐与过氧化氢有较好的协同作用,将其与过氧化氢结合起来用于纸浆漂白,可进一步提高纸浆的白度。Using sulfite bamboo pulp as stock, and oxone as bleaching chemicals, the pulp bleaching experiments were studied. The results showed that it is more efficient to bleach oxygen delignified pulp than un-delignified pulp, oxone can oxide and remove lignin from pulp, reduce pulp Kappa number and make the pulp brighter. The suitable bleaching conditions are： stock concentration is 10%, oxone dosage is 12%, pH is 10.5, temperature is 60℃ and time is 60 min. Oxone has synergistic action with hydrogen peroxide in pulp bleaching, it can improve pulp brightness a lot if using hydrogen peroxide and oxone together in bleaching.
