Some factors influencing the process such as amount of chitosan, deacetylation degree of chitosan, mixing time, setting time have been examined.展开更多
The flocculating property of chitosan on medicinal bentonite suspension has been investigaeted . Some factors such as deacetylation degree and concentration of chitosan and pH were examined. The results showed that ch...The flocculating property of chitosan on medicinal bentonite suspension has been investigaeted . Some factors such as deacetylation degree and concentration of chitosan and pH were examined. The results showed that chitosan has the flocculating property superior to cationic type plolyacrylamide. The adsorption capacity of medicinal bentonite suspension obtained from chitosan flocculation only has a little change as compared with common medicinal bentonite suspension.展开更多
