The value of q e is calculated using equaton (2.1) and the Values needed for the calculaton of Isotherms were recorded in Table . From the above Langmuirs Freunlich and Temkin isotherm plot of methylene blue removal on groundnut shells R 2 value of freundlich constant is 0.960 which is higher than R 2 value of freundlich and Tebkins this means that Langmuir data fted well than Langmuir (0.9436)
