Abstract: Adsorption of the herbicide 2, 4- dichlorophenoxy acetic acid from aqueous solutions onto zeolite mud minerals, was examining. Variables impacting adsorption, for example, pH of the arrangement, adsorbent measurements, molecule estimate, herbicide fixation and temperature have been examined. The adsorption procedure was moderately quick and harmony was accomplished after 120 min. Adsorption harmony information could likewise be depicted by Freundlich models at the centralization of (2, 4-D) who going of (40-200) mg L-1. Thermodynamic fromework, for example, H, G and S were calculate. The kinetic of adsorption process was studied depending on Lagergen, morris- weber and rauschenberg equations.
