摘要
天然高分子絮凝剂具有原料价格低廉、来源广泛、无毒、易于生物降解等优点,通过改性提高其吸附性能是近年来研究的重点。综述了改性纤维素醚类絮凝剂、改性玉米芯絮凝剂、改性竹纤维素絮凝剂、改性稻壳和秸秆纤维素絮凝剂以及改性树材纤维素絮凝剂的制备和应用现状,并展望了纤维素絮凝剂的发展前景。
Natural polymer flocculants have many advantages such as low cost,wide source,non-toxic,easy to be biodegraded,and so on,improving their adsorption performance through modification is the research focus in recent years.The preparation and application of modified cellulose ether folcculant,modified corncob flocculant,modified bamboo cellulose flocculant and modified wood cellulose flocculant were reviewed,and the future development of cellulose flocculants was also prospected.
