Molecular Scattering Of Light

Molecular light scattering in dilute aqueous potassium chloride solutions has been studied. Anomalous (additional) molecular scattering of light is experimentally detected in the concentration interval from 0.001 to 0.004 mole fractions of the electrolyte. The obtained data are compared with the literature data on light scattering in aqueous and non-aqueous solutions of potassium chloride. The absence of additional scattering in the previous works was substantiated.

Dissolution of acrylamide anionic (co)polymers in saline solutions (potassium and sodium chlorides) with concentration of 3.4 mol/l was studied by atomic absorption spectroscopy, optical microscopy, gel-test and capillary viscosimetry. It has been established that with increasing in the content of ionogenic groups and the transition from sodium chloride to potassium chloride solutions the dissolution rate of (co)polymer increases. The concentration of cations of low molecular weight electrolytes is higher in the swollen polymer phase than in the solution in the swelling stage of polymers, the difference in the counter ion content decreases with increasing dissolution time. Comparative analysis of the Huggins constant and the hydrodynamic radii of acrylamide (co)polymers has showed that increase in the interaction in polymer-solvent system is accompanied by the increase in size of macromolecular coils. The Kuhn segment of polymer macromolecules is higher in sodium chloride solutions than in potassium chloride solutions and increases with the decrease in ionogenic group content.
