  • Factors effecting a loss of flocculation activity of

    Abstract. Aluminium, iron III, lead, copper, and zinc ions formed complexes with the carboxyl groups on the polymer, resulting in zero flocculation activity. Nonionic polyacrylamides were unaffected. Viscosityaging of polyacrylamide solutions was observed over a period of several months, but was insufficient to affect the flocculation activity.
