The activated charcoal of olive seeds were used in this study to adsorb the toxin pesticide (Thiophanate-Methyl) from its aqueous solutions. The effect of the parameters such as initial concentration, contact time and temperature have been investigated. A thermodynamic analysis shows that the Thiophanate-Methyl removal by the olive seed’s activated charcoal was an exothermic and spontaneous process. The Langmuir and Freundlich models describe the adsorption isotherms, especially Langmuir model according to correlation coefficients. The results show that removing Thiophanate-Methyl by activated charcoal of olive seed from aqueous solution was very effective and has great potential applications in environmental protection.
