Adsorption parameters of GOX on α-pLys-HAp (40 mg) and ε-pLys-HAp (40 mg) calculated according to Langmuir and Freundlich models.
| Sample | Langmuir parameters | Freundlich parameters | ||||
|---|---|---|---|---|---|---|
| Q m a (mg mg−1) | K L b (mL mg−1) | R 2 | 1/nc | K F d (ng mg−1) | R 2 | |
| α-pLys-HAp (40 mg) | 0.15 | 92 | 0.9999 | 0.105 | 4.02 | 0.8878 |
| ε-pLys-HAp (40 mg) | 0.24 | 31 | 0.9974 | 0.275 | 79.3 | 0.8795 |
a
Q m is the maximum adsorption capacity of GOX at equilibrium.
b
K L is equilibrium constant for the Langmuir models.
c
1/n is Freundlich adsorption intensity constant, while ‘n’ indicates reciprocal of slope value.
d
K F is equilibrium constant for the Freundlich models.
