초록
Gelation of alginate solution was investigated in terms of temperature and concentration of calcium chloride. A diffusion model in a semiinfinite medium was applied to study the gelation rate of alginate solution. The diffusion activation energy of gelation of alginate solution was 18.03Kcal/gmol. The diffusion coefficient of calcium chloride in the alginate solution increased with increasing its concentration and temperature of gelation agent. The concentration variation of gelation agent in growing alginate gel can be predicted theoretically using concentration and temperature of gelation agent.
