木素基絮凝脱色剂的制备及其应用性能研究

The Preparation and Application Performance of Lignin-Base Flocculant

以木质素磺酸钙为原料 ,经接枝、胺甲基化制备了木素基絮凝脱色剂 ,考察了它们对活性艳橙K -G和活性黄X -R的脱色处理效果 ,实验证明 ,在适当的条件下 。

The lignin-base flocculant was prepared with calcium lignosulfonate after grafted and aminomethylation. The decolourizing result of this lignin-base flocculant to two reactive dyes, Reactive Brilliant Orange K-G and Reactive Yellow X-R ,was tested. It was concluded that satisfactory decolourizing results could be obtained under suitable conditions.
