Biosorption equilibrium parameters obtained from Langmuir and Freundlich isotherms.
| Model Parameters | Langmuir | Model Parameters | Freundlich |
|---|---|---|---|
| qmax(mg/g) | 333.33 | n (g/L) | 1.308 |
| KL(L/mg) | 0.002 | KF(mg/g) | 2.72 |
| R2 | 0.978 | R2 | 0.981 |
Notes: qmax: maximum amount of cadmium ion per unit mass of adsorbent; KL: absorption energy; R2: linear correlation coefficients; n: adsorption intensity; KF: adsorption capacity.
