摘　　要： 为了更好地了解绿液对草浆碱回收白泥光学性能的影响,对绿液的成分进行了检测分析,并就其对白泥光学性能的影响进行了研究。结果表明,草浆绿液对光学性能的影响明显,当绿液添加量为100%和20%,白泥白度分别为84.08%ISO和92.66%ISO,差幅比例为10.2%,制备的白泥均偏绿偏黄;草浆绿液中不溶物是影响草浆碱回收白泥光学性能的主要原因,用滤纸处理后的绿液制备白泥白度高,为93.98%ISO,且偏红偏黄;由滤纸处理后绿液制备的白泥白度高出由浊绿液制备白泥白度9.9%ISO,差幅为11.77%;绿液经过絮凝和澄清处理,对碱回收白泥光学性能有明显改善。 To find the effects of green liquor on optical properties of white mud, we characterized the green liquor and studied the effects of elements of green liquor on of white mud.The results showed that the influence of green liquor on optical properties is obvious, when the ratio of green liquor decreases from 100% to 20%, the brightness increases from 84.08% ISO to 92.66% ISO, the spread is 10.2% and the value of a＊ is negative, while the b＊ is positive. And the most responsibilities for the optical properties decreasing is insoluble matter. When the green liquor treated by filter paper, the brightness of white mud is 93.98% ISO, and both the a＊ and b＊ are positive, while the untreated, the brightness decreases to 84.08% ISO, the spread is 11.77%. The optical properties are significantly improved by clarification and flocculation.
