Correlation of type II adsorption isotherms of water contaminants using modified BET equations

The BET equation is commonly used to describe type II sigmoid isotherms of water contaminants. However, there are some that do not agree with the equation. In this paper, three modified equations (Aguerre–Suarez–Viollaz, Pantuso–Tolaba–Aguerre, and Aranovich–Donohue) evaluated against published isotherm data dysprosium, reactive blue 5G, naphthenic acid. cases studied, shown outperform original Aranovich–Donohue a promising model, offering accurate correlations statistically significant parameter estimates. particular, it very effective in tracing atypical curve shapes 5G acid isotherms. Although has attracted much attention, practical alternative widely for correlating adsorption
