Clinoptilolite, a natural zeolite, was used for the synthesis of a high surface area clinoptilolite-iron oxide system (Clin–Fe system) to be used for the removal of Mn2+ and Zn2+ ions from drinking water samples. The new system was obtained by adding natural clinoptilolite to an iron nitrate solutio

Synthetic chelating agents are used to increase the phytoextraction of metals from contaminated soils, however the increased bioavailability of the metals may increases the potential risk of groundwater contamination. In this study, 4 mmol EDTA kg–1 was applied using four application methods to a Cd
