The following data were used: From the above Langmuir, Freunlich and Temkin isotherm plot of congo red dye removal using sorghum husk, R 2 value of freundlich constant was 0.9850 which was higher than R 2 value of freundlich and Tebkin, this means that Langmuir data fied well than Langmuir (0.868) and Temkin (0.880) data in the adsorption process. That shows that adsorption process is a multilayer adsorption process.
