This paper presents research on phenoxyacid pesticides removal using sorption methods on activated carbons. It was noted, that physico-chemical properties of adsorbent and adsorbate as well as parameters of the process have influence on adsorption of pesticides, derivatives of phenoxyacetic acid on carbon. The experimental data were analyzed by the Freundlich isotherm. The best for remove from water on carbon NP-5 was 2,4-D. Equilibrium data fitted well with the Freundlich model with maximum adsorption capacity of NP-5 carbon. The exemplary sorption capacity at equilibrium concentration 10 mg L(-1) were: 2,4-D 70 mg g(-1), MCPA 2 mg g(-1), MCPP 0.5 mg g(-1). The results indicated that coconut shell-based NP-5 carbon is most effective for the adsorption of phenoxyacetic acid from aqueous solutions.
