新型纤维素絮凝剂的制备与絮凝作用

Synthesis and Flocculating Effect of Flocculating Agent of Cellulose

本文制备了具有絮凝作用的羟乙基纤维素衍生物,并由FTIR加以证实。同时考察了反应条件,如羟乙基纤维素的用量、氧化剂的用量及反应时间对产物凝絮效果的影响。结果表明,在本实验范围内,HEC和HC lO的用量越大,反应时间越长,产物中的-COOH含量越高,凝絮效果越好,但H2O2用量过大时会造成纤维素主链的断裂,凝絮效果下降。

In this paper, the derivative of hydroxylethylcellulose （HEC） with flocculating effect was synthesized and characterized by FTIR. The influences of reaction conditions, such as the charges of HEC,H2O2 and HClO and reaction time, on flocculating effects were investigated. The HC10, and longer reaction time resulted in higher - COOH the charge of H2O2 was too high, the chain of cellulose was results show that higher charges of HEC, H2O2 and content and better flocculating effect. However, when broken and the flocculating effect decreased.
