摘要
本文研究了几种非过程金属元素在纸浆中的富集规律,其中包括富集时间与富集量的关系、金属离子添加量与富集量的关系、pH值对富集量的影响以及不同硬度的纸浆中金属离子富集量的区别,并分析估计了一下纸浆中每种非过程金属离子的最大富集量。
The enrichment rules of several non-process metal elements in pulp system were studied. These include the relation between the enriehiment capacity and the enrichment time, the relation between the enrichment capacity and metal ions accession quantity. At the same time, the pH value and the hardness of the pulp have also affected the enrichment of non-process elements. The largest enrichment capacity of each metal ion was also estimated.
