The experimental data of the adsorption isotherms
were adjusted to the mathematical models GAB, BET, Henderson, and Oswin, as described in Eqs.
The adsorption isotherms
were studied through various models such as the Langmuir, Freundlich and BET isotherms.
Following the adsorption isotherms
, the adsorbent was separated from the solution by filtration with quantitative filter paper, washed with ultrapure water and oven-dried at 60[degrees]C for 24 hours.
The equations obtained for Langmuir adsorption isotherms
for the chemical and natural adsorbents are shown in Table 2.
Langmuir Adsorption Isotherm
Langmuir adsorption isotherm
is valid for monolayer formation of adsorbate on the surface of adsorbent.
Equilibrium data commonly known as adsorption isotherms
are basic requirement for the analysis and design of adsorption system (Aksu and Isoglu 2006).
The adsorption isotherm
data were fitted well to the Langmuir model from Langmuir model equations.
Adsorption properties and porous structure of sulfuric acid treated bentonites determined by the adsorption isotherms
of benzene vapor, Journal of the Serbian Chemical Society 70: 33-40.
Determined the optimum conditions for the Cr adsorption by the crambe seed pie, and they were used for constructing the adsorption isotherms
The adsorption of MAMT on the base alloy was found to be through physisorption, obeying Langmuir's adsorption isotherm
An adsorption isotherm
is characterized by certain constant values, which express the surface properties and affinity of the adsorbent and can also be used to compare the adsorption capacities of various adsorbent for different pollutants.
studies were carried out with different adsorbent doses ranging from 1 to 6 g/100 mL while maintaining the initial chromium concentration at 5 mg/L.
