The practical ranges for monomer concentration are stock solutions of 30-40%, with different ratios of acrylamide monomer to crosslinker. The designations 19:1, 29:1 or 37.5:1 on acrylamide/bis solutions represent crosslink ratios 5%, 3.3% and 2.7% (the most common crosslinker concentration for protein separations).

Method for preparing high molecular weight polyacrylamide

Polyacrylamide powder can’t be directly added to sewage. It must be dissolved in water before use, and then use polyacrylamide solution for sewage treatment. Use clean water to dissolve PAM powder. Generally, just use water at room temperature, no need to heat it. However, the dissolution is very slow when the water temperature is lower than
