The intrinsic viscosity is determined for sodium alginate sample, a peak in the curve of reduced viscosity vs sodium alginate concentration is observed when diluted with a fixed low ionic strength solution, and the measurements are carried out in aqueous KCl solutions of various ionic strengths. On the basis of this study on sodium alginate over the ionic strength range from2×10-5 mol L-1 to 0.5 mol•L- 1, it can conclude that the contribution of electroviscous effect to the polyelectrolyte solution viscosity may be explained by the electrostatic persistence length.
