摘要：综述了淀粉大分子上悬挂不同类型胺基如伯、仲、叔以及季铵基基团的阳离子淀粉絮凝剂的制备方法和性能评价。并探讨了各种影响因素如化学结构、絮凝剂剂量、pH值、相对分子质量、胺基基团类型以及氮含量等对絮凝效果的影响。结果表明,在淀粉大分子上悬挂季铵基团的阳离子淀粉絮凝剂效果最好。
In this paper, prepared methods and evaluation of properties as flocculant of cationic starch derivatives bearing various amine type or amino groups, i. e. primary, secondary, tertiary quuaternary ammonium salts were reviewed. The various factors, i. e. Chemical structures, flocculant dose, pH - value, molecular weights, types of amino groups and nitrogen content etc. , and compand flocculation of various ferric soaps with cationic starch, zeetag and Floe - AID were discussed .
