What the correct calcultions of D-R isotherm model parameters, concerning the units of Ce and Qe in mg/L and mg/g to calculate adsorption Energy in KJ/mol
Aida Fekaouni
Dear Tarek Sabry
the correct calculations of D-R isotherm model parameters (ln Ce and ln qe without units)
Dubinin−Radushkevich model:𝑞𝑒=𝑞maxexp− βε** non-lineair
ln qe = ln qmax− β ε** linear
ε = RTln [1+(1/Ce)]
The maximum adsorption energy, E (kJ/mol), provides information about the adsorption process. If the value of E is between 8 and 16 kJ/mol, the adsorption is a chemical process; however, if E
