The reactivity and kinetic characteristic of laccase/mediator towards unbleached kraft pulp under different conditions were studied.
采用溶解氧分析仪对漆酶和漆酶/介体处理未漂KP浆过程中的氧气质量浓度进行测定,研究了不同条件下漆酶/介体处理纸浆的反应性能,通过对实际动力学曲线的拟合,建立了漆酶/介体体系催化氧化反应的动力学模型。
The results indicate that yield of screened pulp is almost unaltered, brightness of unbleached pulp is improved 8.
0%,在温度90℃时处理30min可以得到满意的结果,在纸浆得率几乎不变的前提下,烧碱蒽醌法蒸煮未漂浆白度提高了8。
