INVESTIGATION OF THE MOLECULAR STRUCTURE OF THE "POLYACRYLAMIDE FLOCCULANT–H2O" SYSTEM FROM VISCOSIMETRY DATA

The dynamic viscosity of the system "polyacrylamide fl occulant–H₂O" has been measured in the temperature interval 277–313 K. The dependence of the particle size on the ionic force of solutions has been investigated. The quantities characterizing the physicochemical properties of particles, such as the thickness of the diffusion layer and of the hydration sheath, have been determined. The interaction energy of particles of the high-molecular-weight compound in the solution has been studied. Results of purifi cation of model solutions of industrial wastewater have been given, which were obtained with the fractional-fl occulation technique. The characteristic of the investigation method in question has been presented, the basic classes of reactants have been described, and the mode of action of the substances has been substantiated.
