Abstract：Objective:To study the hygroscopic behavior of Chinese herbal medicine ingredients by applying adsorption kinetic model.Methods:Four adsorption kinetics models were applied to simulate the hygroscopic behavior of Chinese medicinal materials by nonlinear regression,and the influences of environmental factors on moisture absorption behavior were also analyzed.Results:Pseudo first order kinetic equation,pseudo second order kinetic equation and Elovich equation can simulate the hygroscopic dynamic behavior of Chinese medicine raw materials.Among these,Pseudo first order kinetic equation has the best model.Environmental factors have obvious influence on moisture absorption behavior of Chinese herbal medicine.The moisture absorption process of Chinese herbal medicine accords with Arrhenius equation,and temperature has obvious influence on its hygroscopic behavior.Conclusion:The moisture adsorption in Chinese herbal medicine ingredients conforms to the Pseudo first order kinetic equation.
