It indicated that this
isotherm model is not followed at such high temperature.
Moisture sorption
isotherm characteristics of potatoes at four temperatures.
The Langmuir adsorption
isotherm (physical adsorption model) assumes monolayer adsorption and the linear form of the Langmuir
isotherm is (Langmuir, 1918)
Given these reasons, as well as the importance of understanding the hygroscopicity of agricultural products, the objective of this study was to determine the adsorption
isotherms of roasted coffee ground at different particle sizes.
Temkin adsorption
isotherm assumes that the heat of adsorption of all the molecules in the layer is inversely proportional to coverage of the adsorbent surface which might be attributed to adsorbate species - adsorbent interactions.
L] values indicate the applicability of
isotherm model.
Table-2: Coefficient of Langmuir and Freundlich
Isotherm for DB-K2RL.
The values calculated using formula (2) for each adsorbent are presented in Table 2, and at their values the classical (in coordinates A - C) and linearized (in coordinates C/A - C) adsorption
isotherms are constructed (Fig.
The Dubinin-Radushkevich (D-R)
isotherm [38] equation is described as following:
Kinetic and
isotherms of biosorption of Hg(II) using citric acid treated residual materials
1) The Freundlich
isotherm model can be applied to non-ideal sorption on heterogeneous surfaces as well as multilayer sorption and is expressed by the following Eq.
