摘要
Abstract
Fick＇ s second law was applied to investigate the mechanism of potassium sorbate release from chitosan films.The mathematical model was established.The result showed that,the diffusion coefficient D decreased with the increase of chitosan concentration when the initial concentration of potassium sorbate was constant. The diffusion coefficient D increased with the increase of potassium sorbate concentration when the concentration of chitosan was constant.The mechanisms of potassium sorbate diffusion through chitosan films were mainly Fickian and determined by the power law model M1/M∞=k×t^n.关键词
