R2
|
1 |
R2 is the regression coefficient |
|
RL
|
0.985 |
RL value lies between 0 and 1 for
favorable adsorption; RL higher than 1
means unfavorable adsorption; RL equal
to 1 represents linear adsorption; RL =
0 means the adsorption process is irreversible |
|
Qmax (mg/g) |
105 |
Qmax is the maximum adsorption
capacity of the adsorbent |
|
KL (L/mg) |
0.001511 |
KL is the constant
of the Langmuir
model |
| Freundlich |
R2
|
1 |
R2 is the regression coefficient |
| 1/n
|
0.9999 |
Kf and n are the
Freundlich constants and give an indication about the maximum adsorption
capacity |
|
KF (mg/g) |
2.500 |
if 1/n is less
than 0.5, the adsorption would be easily carried out |
| |
|
if 1/n is larger
than 0.5, the adsorption is difficult |
