英文摘要: Abstract(#br)The chitosan (CTS) characterized with many functional amino and hydroxyl groups has been the research focus on flocculants preparation and synthesis because of the facile grafting and modification to enhance and enlarge its original functions. In this study, a new type of graft modified flocculant CTS-g-PAA and its combination with kaolin have been developed for the treatment of acid blue 83 (AB 83). The CTS-g-PAA prepared by ultrasonic initiation of acrylamide (AM), 3-Acrylamide propyltrimethylammonium chloride (AATPAC) and CTS. The factors affecting CTS-g-PAA molecular weight and CTS graft ratio were examined to have a better understanding and comprehending of the ultrasonic initiated polymerization. The structure and morphological characteristics of CTS-g-PAA were...
