研究了氧化白液(OWL)在过氧化氢漂白中对纸浆白度的影响。研究了双氧水浓度、漂白温度和漂白时间的合理设置。为了产生必要的实验运行，提出了中心复合设计(CCD)。用回归分析确定相关方程。优化确定了要获得83%的目标白度，OWL和氢氧化钠的体积比应为50：50。当过氧化氢浓度为6.9g/kg，漂白温度为90oC，漂白时间为75分钟时，应使用此比例。
This paper aims to study the effect of using Oxidized White Liquor (OWL) on pulp brightness in peroxide bleaching. The proper setting of the concentration of hydrogen peroxide, the bleaching temperature, and the bleaching time was also studied. The Central Composite Design (CCD) was proposed to generate necessary experimental runs. Regression analysis was used to determine the relationship equation. Optimization helped determine that to obtain the targeted brightness of 83%, the ratio between the volume of OWL and sodium hydroxide should be 50:50. This ratio should be used with a concentration of hydrogen peroxide at 6.9 g/kg, a bleaching temperature of 90 oC and a bleaching time of 75 minutes.
