o:3539 Surface modification of the natural clinoptilolite for its potential use for the nitrate removal from water media en Abstract: The natural zeolitic tuff, containing more than 70 % clinoptilolite (CLI), has been investigated as a starting material for obtaining a low cost adsorbent for the removal nitrate ions from water media. 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. clinoptilolite, zeolite modification, adsorption, nitrate removal 1552100 978-86-82139-41-6 2023-12-15T08:55:50.942Z 44 no 46 Jelena Pavlović Institute of Soil Science 0000-0001-9424-1080 46 Jelena Milenković 46 Đorđe Stojaković 46 Nevenka Rajić application/pdf 718199 https://unilib.phaidrabg.rs/o:3539 no yes 1 70 92000004 71A05 5th Serbian-Croatian-Slovenian Symposium on Zeolites 2013
