Paper Title:
The Influential Factors of Preparing PAM Coagulants with High Molar Weight
  Abstract

In order to obtain high molecular weight polyacrylamide coagulant, preparation of the initial reaction temperature, dose of the azo initiator agent, ratio of different redox initiator agent, pH and other affecting factors were investigated and the results show: the best initial reaction temperature is 15 °C, the mass of azo initiator is 0.4g, the ratio of redox initiator is 3:2, in which oxidant ammonium persulfate is 0.75840 g/L 0.6mL, the best pH value is 8. By taking the best value of all factors, we can get polyacrylamide coagulant of 1.315 million viscosity molecular weight materials and 76.7 % effective solids after 2 drying processes.
