The reaction mechanism of sodium hypochlorite oxidization method (turbidity method) for the determination of partially hydrolyzed polyacrylamide is described.The effects of molecular weight of polyacrylamide,concentration of sodium hypochlorite solution and reaction time on the absorbance have been studied in detail. To minimize the interferences of factors such as alkali, surfactant, high pH, high viscosity,and enrich sulfide and sulfite in alkali surfactant polymer flooding produced liquid at Daqing Oilfield,ammonium persulfate turbidity method is first introduced in the determination of HPAM.
