| Abstract: | The effect of Fe 2 concentration and pH values on the stability of partially hydrolyzed polyacrylamide(PHPAM)was investigated The lower the pH value is,the higher will be the loss in the viscosity of PHPAM To keep the viscosity of PHPAM solution constant for a certain period,when the concentration of Fe 2 is zero to 1 0 mg/L,and pH value is about 8 0,the concentration of HCHO must be kept at higher than 400 mg/L The concentration of HCHO does not decrease within 20 days under this condition |
