Dubinin-Radushkevich Isotherm Non-Linear Analysis
Description
Dubinin-Radushkevich isotherm model is being utilized to define adsorption energy mechanisms with Gaussian distribution onto heterogeneous surfaces. Specifically, this model works well with an intermediate range of adsorbate concentrations because it shows abnormal asymptotic behavior and is unable to forecast Henry's Law at low pressure.
