%description
The Langmuir and Freundlich adsorption isotherms are pivotal in
characterizing adsorption processes, essential across various scientific
disciplines. Proper interpretation of adsorption isotherms involves robust
fitting of data to the models, accurate estimation of parameters, and
efficiency evaluation of the models, both in linear and non-linear forms.
For researchers and practitioners in the fields of chemistry,
environmental science, soil science, and engineering, a comprehensive
package that satisfies all these requirements would be ideal for accurate
and efficient analysis of adsorption data, precise model selection and
validation for rigorous scientific inquiry and real-world applications.
Details can be found in Langmuir (1918) <doi:10.1021/ja02242a004> and
Giles (1973) <doi:10.1111/j.1478-4408.1973.tb03158.x>.
