Sodium alginate molecular weight determination

Wedlock, D. J., Fasihuddin, B. A., and Phillips, G. O. (1986). Comparison of molecular weight determination of sodium alginate by sedimentation-diffusion and light scattering. Int. J. Biol. Macromol. 8 57-61. [Pg.220]

The molecular weight of the sodium salt of alginic acid has been determined by measurements of osmotic pressure in sodium chloride solution.88 The n/C versus C curve was found to be independent of salt concentration for values between 0.2 N and 0.5 JV, and the slope of the curve was the same for a series of seven fractions with values of molecular weight between 48,000 and 186,000 (220-860 D-mannuronic acid units). Intrinsic viscosity measurements showed the coefficient a in the modified Staudinger s equation88 to be 1.0 and the approximate value of Km to be 15(10)-4. [Pg.318]
