how much is polyacrylamide environmental impact from United Kingdom
Potentiometric titrations in water of high‐molecular‐weight partly hydrolyzed polyacrylamides were analyzed by the Lifson—Katchalsky rodlike model. A fair concordance was found between theory and experimental curves with pK0 of acid functions of about 4.75 when 0 < τ < 0.49. Two methods were derived to calculate the parameter n of the extended Henderson‐Hasselbach equation by using a
High-molecular-weight partially hydrolyzed polyacrylamides are widely used in enhanced oil recovery. Mechanical degradation of these polymers as a result of flow through pumps, chokes, valves and at the sand face has been recently reported to have a negative impact on the application.
