R2 and constants for Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherm models.
| Langmuir | Freundlich | Temkin | Dubinin–Radushkevich | |||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| qmax (mg/g) | KL (l/mg) | R2 | kf (mg/g) | 1/n | R2 | kt (l/mg) | B (J/mol) | R2 | qmax (mg/g) | E (KJ/mol) | kDR (mol2/kj2) | R2 |
| 52.9100529 | 0.6 | 0.9995 | 37.00837363 | 0.0641 | 0.9274 | 1.88 | 2.9132 | 0.9381 | 51.5 | 1290.9 | 3.00E-07 | 0.9655 |
∗Where qmax is the maximum adsorption capacity (mg/g), KL is Langmuir constant (l/mg), Kf is Freundlich constant (mg/g), kt is Temkin constant (l/mg), kDR is Dubinin–Radushkevich isotherm constant(mol2/kj2), 1/n is the empirical constant, R2 is the regression correlation coefficient and E is energy of adsorption.
