| Abstract: | In this paper, we determined the viscosity and conductivity of 3wt% sodium alginate solution mixed with various quantities of inorganic salt and at different temperatures.Together with IR spectrum, we predicated the structural alternation during the process of sol-gel transition. A qualitative explanation was suggested on the difference of gelation ability between Cu2+ an Co2+ cations. |
