摘要
通过对造纸废水中木质素的研究表明,用甲基异丁基甲酮、乙醇和水的混合溶液对造纸废水所产生的污泥进行提取,将其中的木质素进行回收,并利用木质素的吸附功能,将提取的木质素对三价铬离子进行吸附,三价铬离子被完全吸收.
The lignin of the papermaking wastewater was regarded as researching object.The experiment of lignin reclaimed,the mixed solution methyl isobutyl ketone﹑alcohol and water(Volume ratio 5.5∶ 3∶ 4) was used in order to distill lignin.lignin have absorbable function,In the same time,we can use lignin reclaimed to absorb Cr(Ⅲ).Cr(Ⅲ) was eliminated by lignin completely.
