Surface Modified Zeolite And Other Nanogeocomposites: An Effective And Sustainable Natural Resources For The Removal Of Pollutants

Abstract

Considering the proactive approach to green agenda and sustainable development goals the use of natural resources instead of non-environmentally friendly processed adsorbents is one of the way how to save environment as well as not to widespread industrial pollution. EU Directive 2013/39/EU recommends to monitor in waters already 45 priority compounds incl. pharmaceuticals. Among the traditional geomaterials used also in biomedicine as pharmaceutical excipients or nanotransporters (nanobots) occurs lately also clinoptilolite-rich tuff with hydrophobized external surface, as potential representant of tectosilicates, able effectively remove much broader range of environmental pollutants than some other natural or commercial adsorbents. This review deals with some aspects of water pollutants (cefazoline, acid red, cresol and decane) removal using the clinoptilolite-rich tuff and some other perspective natural resources regarding to conventional adsorbents.
