Will the viscosity of anionic polyacrylamide be affected by the pH value?

Anionic polyacrylamide is used in wastewater treatment, will the viscosity of anionic polyacrylamide be affected by the pH value?

Will the viscosity of anionic polyacrylamide be affected by the pH value? The viscosity of the Anionic polyacrylamide PAM aqueous solution is not affected by the concentration, temperature, pH value, shear rate and polymer molecular weight of the solution as follows.
1. Effect of pH value The viscosity of non-ionic PAM polyacrylamide solution is not significantly affected by pH value. But when the pH value is above 10, the viscosity of the polymer increases rapidly due to hydrolysis. This is where the effect of the pH value becomes apparent.
2. Effect of solution concentration For high molecular weight polyacrylamide, even if the concentration is a few percent, the solution is quite viscous, and it is difficult to handle when the concentration exceeds 10%. Raising the temperature can reduce the viscosity but not significantly.

Anionic polyacrylamide water treatment agent is an essential chemical substance in the process of industrial water, water supply and sewage treatment. By using these chemical substances, the water level can meet specific quality requirements. Its main function is to control scale and sludge formation, reduce foam, reduce contact with water, remove floating solids and water toxic substances from material erosion, decolorize and soften water quality, etc. At present, due to the significant increase in water consumption in all countries in the world, various environmental protection laws and regulations have been enacted and the requirements are becoming stricter, so the effective water treatment agents are increasing rapidly.
