A discussion on linear and non-linear forms of Thomas equation for fixed-bed adsorption column modeling

The Thomas model is the most common equation to describe dynamics of fixed-bed adsorption columns. However, its parameters’ validity strongly depends on region breakthrough curve considered for data fitting. A rigorous analysis based different error functions was carried out determine accuracy both linear and non-linear forms model. proved be more robust less susceptible experimental error, with than 0.5% deviation in qTh calculation. complete statistical should fitting if regression preferred.
