Biblioteca de Adsorção: Uma Ferramenta Interativa Baseada na Web para Equilíbrio Integrado e Modelagem Cinética de Dados de Adsorção

Adsorption is a fundamental separation process in water treatment, environmental remediation, and industrial applications. The design and optimization of adsorption systems critically depend on equilibrium isotherm models and kinetic models that describe transient behavior. Despite the ubiquity of these models in the literature, researchers and engineers face significant barriers: commercial software is expensive, open-source tools require programming expertise, and manual calculations are error-prone and difficult to reproduce. This work presents an interactive, open-source web platform that unifies the analysis of equilibrium isotherms and kinetics of batch and fixed-column adsorption. The tool can be accessed at https://adsorptionmodels.streamlit.app/ and implements seven classical isotherm models, eight kinetic models, automatic estimation of confidence intervals (95%), ranking by Akaike Information Criterion, and generation of reproducible PDF reports and Python scripts. Validation on sample data demonstrates that the platform provides analyses in minutes with statistical rigor and clear communication of uncertainty, reducing the barrier to rigorous adsorption modeling in research and engineering.
