Determination of polyacrylamide concentration in adsorption experiments Processing and applications
A viscometric and a modified nephelometric method for the determination of high-molecular-weight polyacrylamide (PAA) content in aqueous solutions have been elaborated. They have been applied in the determination of adsorption isotherms of PAA from aqueous solutions on colloidal Agl particles. The suitability of both methods for studies on PAA adsorption in highly dispersed systems has been compared and it has been found that viscometric method gives better results.
