Thesis Name£º Study on synthesis of fastª²solving polyacrylamide Usage£º synthesis and application Keyword£º 123 Remarks£º Study on synthesis of fastª²solving polyacrylamide and application WANG Guang-hua1£¬LI Wen-bing1,2 (1.College of Chemical Engineering,Resources & Environment,WUST, Wuhan 430081,China£» (2.School of Life Science & Technology,Huazhong University of Science and Technology, Wuhan 430074£¬ China) Abstract£ºThe fast-solving polyacrylamide(PAM) was prepared by microemulsion polymerization, and the reason of fastª²solving was also analysed. The properties of these three PAMs were studied,that were used to treat suspendings and COD of the waste water. The results showed that the dissolvability of labª²PAM was better than the other two products and the dissolution time was up to 5.5min.In addition,the suspending removal effect of labª²PAM was equal or better than that of France PAM,and obviously exceeded that of homeª²grown PAM,especially the suspending removal percentage was 98% in waste water of pudding plant.The lab-PAM could substitute the France PAM in treating steel waste water. It was not ideal to remove COD of effluent via adding these three PAMs products. Key words£ºpolyacrylamide;microemulsion;flocculating agent;effluent treatment Original file£º No File
