The clinoptilolite surface was modified by a simple method with iron(III), aluminum, manganese(IV) and magnesium oxide in order to make the negatively charged zeolite surface accessible for nitrate adsorption. Preliminary results indicate that the best adsorption capacity towards nitrate are shown by the zeolite samples containing magnesium and iron(III) oxide particles. 2013 clinoptilolite, zeolite modification, adsorption, nitrate removal info:eu-repo/semantics/conferenceProceedings 5th Serbian-Croatian-Slovenian Symposium on Zeolites All rights reserved eng Pavlović, Jelena Milenković, Jelena Stojaković, Đorđe Rajić, Nevenka
