The values of the correlation coefficient of biosorbent estimated for langmuir and freundlich isotherm were both high 0.99908 and 0.99994 accordingly. But 1/n value were not between 0 to 1 for freundlich model. But langmuir constant RL value (0.89) showed favorability. So which isotherm would fit better?
Balram Lohan
langmuir isotherm fit is better according to your given values
langmuir isotherm:
The RL value depicts whether the isotherm is favourable (0 1), linear (RL=1) or irreversible (RL=0).
Freundlich isotherm:
The value of 1/n indicates the isotherm to be favorable (0

Of cource it could be better to fit with langmuir mathematical model regarding this particular case.
