| Abstract: | In this paper, the affections resulted by several metallic catlons upon the relativeviscosity during the process of gel formation of the sodium alginate agucous solution were studied. At thesame time, the mechanism about the sol-gel phase transition of alginic acid caused by the addition ofsalts was investigated by NMR techniques. |

| Keywords: | alginic acid sol-gel relative viscosity resonance peak |
