Research Isothermal Medicinal Herbal

The paper studied the sorption and desorption of water vapor samples medicinal herbs Leonurus and mother-and-stepmother. Analysis of sorption isotherms and desorption is important to clarify the characteristics of the forms of moisture due to the material. On the basis of sorption isotherms of water vapor samples medicinal herbs Brunauer, Emmett and Taylor (BET) equation have been calculated monolayer capacity, specific surface area, total pore volume and the radius of the capillary. Capillary-porous structure of the sample is shown at 25 0C of dried medicinal herbs
