WebThe results showed that the suitable model is the BET Isotherm Adsorption model with parameter values, namely the BET isotherm adsorption constant value (C BET ) of … The Henry adsorption constant is the constant appearing in the linear adsorption isotherm, which formally resembles Henry's law; therefore, it is also called Henry's adsorption isotherm. It is named after British chemist William Henry. This is the simplest adsorption isotherm in that the amount of the surface adsorbate is represented to be proportional to the partial pressure of the adsorptive gas:
