The contents and distribution of metal ions in reed,wheat straw,bamboo and baggage are studied by means of atomic absorption spectrometer. The results show that there are many kinds of metal elements in each raw material,Mn,Fe,Cu,Ca,Mg,Al,Si and Ni etc are the major elements. In reed,the content of Mn,Cu,Fe or Al is higher than that in other raw material. As compared with other material,the content of Mn or Fe in wheat straw is slightly lower,and that of Si or Ni is the highest. In general,the metal contents...

The contents and distribution of metal ions in reed,wheat straw,bamboo and baggage are studied by means of atomic absorption spectrometer. The results show that there are many kinds of metal elements in each raw material,Mn,Fe,Cu,Ca,Mg,Al,Si and Ni etc are the major elements. In reed,the content of Mn,Cu,Fe or Al is higher than that in other raw material. As compared with other material,the content of Mn or Fe in wheat straw is slightly lower,and that of Si or Ni is the highest. In general,the metal contents in smaller dimension fragments of raw material are obviously higher than that in bigger dimension one. In wheat straw,content of Mn or Fe in stalks is higher than that in other parts. The distribution of metal ions in unbleached Soda-AQ pulp of bamboo and reed are also studied. The experiments reveal that an enhanced pretreatment of raw material,resulting in a substantial decrease in the knots,the ears,the leaves,and the ground tissue as well as other nonfiber cells in straw raw material,will play an important role in upgrading the alkaline recover efficiency of black liquor and in decreasing pollution. It will also bring about the significant improvement on the distribution of metal ions and bleaching effect of straw pulp.

用原子吸收光谱法测定常用造纸草类原料的金属元素含量及分布 ,结果表明 ,每种原料中都含有复杂的金属元素 ,各种原料的金属元素分布特点不同。对竹子和芦苇两种Soda AQ法未漂浆中金属离子分布的初布研究结果表明 ,未漂浆中的金属离子与原料中的金属离子有很好的对应关系。加强草类原料的备料 ,尽量除去原料中的草叶、草节、草穗等组分及薄壁细胞等非纤维细胞 ,不但对提高草浆黑液的提取率及碱回收效果 ,降低污染等有好处 ,对降低未漂浆中过渡金属离子的含量 ,改善金属离子的分布状况 ,提高漂白效果 ,节约漂剂 ,提高漂浆质量等方面也具有重大意义
