Quaternary Ammonium Salt Modified with Vegetable Tannin as Flocculants: Preparation and Property Evaluation

用植物单宁和二甲胺、甲醛及环氧氯丙烷进行季铵化反应 ,制得了JK A和JK B两种阳离子絮凝剂。测试了产品的红外光谱 。

This paper described a kind of natural material based organic flocculants with emphasis on the preparation and evaluation of flocculation properties. Two cationic flocculants (JK A and JK B) were made through quaterisation, and the products were tested by infrared spectrums to determine the completion of quaerisation. Evaluation was made on the basis of a series of jar tests of sewage flocculation for comparing the flocculants each other and with other flocculants such as aluminum sulfates, ferric chlorides and chitosan.
