The adsorption of MCPA and 2,4-D on the activated carbon Filtrasorb 300 was studied. The adsorption isotherms of herbicides
from aqueous solutions were measured over a wide range of solute concentrations and at different temperatures. The experimental
equilibrium data were analyzed by the Langmuir–Freundlich isotherm taking into account the energetic heterogeneity of adsorption
system. The effect of temperature and herbicide properties on its uptake was discussed. The thermal analysis was applied in
order to find the differences in herbicide interactions with carbon surface. The kinetic dependences were measured and the
relations between solute properties and adsorption rate were discussed.
