Abstract
This work aims to model the adsorption isotherms and study the essential thermodynamic properties of Taraxacum Officinale’ powder during the moisture adsorption phenomenon at three temperatures 30, 40, and 50°C. The results have been determined by the application of the thermodynamics physical principles to the equilibrium data, which are experimentally measured. The estimated values of the isokinetic and harmonic temperatures and the Gibbs free energy change revealed that the sorption process is non-spontaneous and enthalpy driven.
Highlights
The Taraxacum Officinale powder is a therapeutic treatment whose benefits have been discovered since ancient times
We can note from this table that Guggenheim Anderson-Boer (GAB) model is suitable to fit the experimental data of moisture adsorption of Taraxacum Officinale’s powder at three temperatures 30,40 50 °C, with a correlation coefficient (r = 0.9984, r = 0.9985, r = 0.9988), and the standard error of estimate (SEH = 1.8786, SEH = 1.6797, SEH = 1.4255) respectively. what’s more the table displays that the equilibrium water content at the saturation level of the monolayer is between 7.6767 and 8.0019 (%d.b)
This work has been devoted to the study of adsorption isotherms and the thermodynamic properties of the Taraxacum Officinale leaves powder
Summary
The Taraxacum Officinale powder is a therapeutic treatment whose benefits have been discovered since ancient times. The benefits of this powder were proven only in the sixteenth century [1]. Taraxacum Officinale has many properties that can act on the liver. They are effective for liver failure and seizures. It can be considered as a natural diuretic and depurative. It is useful against certain skin diseases [2,3,4]
