摘要
研究和讨论了一些主要过程参数的影响和某些金属离子对甲脒亚磺酸(FAS)在纸浆漂白中的影响,同时对FAS漂白过程中添加螯合剂的作用做了深入研究,结果表明螯合剂的加入能改善FAS的漂白能力.
The influence of several main process variables and some metals ions on pulp bleaching with formamidine sulphinic acid (FAS) was investigated and discussed. The necessity and function of some chelates for FAS bleaching was studied. It is concluded that addition of chelates is beneficial to improve the brightening ability of FAS.
