The biodegradable synthetic polymer poly(ε‐caprolactone) was investigated as a substrate for denitrification. This substrate may also act as an adsorbent for two pesticides, i. e., atrazine and simazine, from water. The equilibrium was studied at 25, 35 and 45°C. The results were correlated using the Langmuir and Freundlich adsorption models. The total capacities of the adsorbent were defined from experimental data for atrazine (10.98 mg g –1 ) and simazine (27.54 mg g –1 ). The effect of temperature on the model constants and the thermodynamics of adsorption were investigated. The evaluation of the development of adsorption was achieved by assuming a pseudo‐second order chemical reaction.
