Kinetics of the Cross-Linking of Polyacrylamide with Cr(III) - Analysis of Possible Mechanisms
The reaction between chromium(III) and partially hydrolyzed polyacrylamide (HPAM) has been investigated by UV-visible spectroscopy. We found that the reaction between Cr(III) and HPAM can show a biphasic response. Initial rate experiments show saturation kinetics. The influence of reactant concentrations on the kinetics has been studied, and possible mechanisms consistent with the experimentally observed kinetic behavior have been derived.
