20.500.12556/DiRROS-13715 Preparation and characterization of the sulfur-impregnated natural zeolite clinoptilolite for Hg(II) removal fromaqueous solutions Sulfur-impregnated zeolite has been obtained from the natural zeolite clinoptilolite by chemical modification with Na2S at 150 °C. The purpose of zeolite impregnation was to enhance the sorption of Hg(II) from aqueous solutions. Chemical analysis, acid and basic properties determined by Bohem’s method, chemical behavior at different pHo values, zeta potential, cation-exchange capacity (CEC), specific surface area, X-ray powder diffraction (XRPD), scanning electron microscopy with energy-dispersive X-ray analysis (SEM-EDS), Fourier transform infrared spectroscopy (FTIR), as well as thermogravimetry with derivative thermogravimetry (TG-DTG) were used for detailed comparative mineralogical and physico-chemical characterization of natural and sulfur-impregnated zeolites. zeolit klinoptilolit živo srebro onesnaženje okolja true false true MDPI Angleški jezik Ni določen Delo ni kategorizirano 2021-03-03 09:31:27 2022-03-03 13:47:24 2022-08-19 03:36:15 0000-00-00 00:00:00 2021 0 0 Soavtorji: Martin Gaberšek, Aleksandra Daković and Ivona Nuić; 25 no. 2 vol. 9 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 504.5 2227-9717 10.3390/pr9020217 50306563 523353113 processes-09-00217.pdf processes-09-00217.pdf 1 FC9E79A8D72B0E7CDA265D36E6136F48 3056267f59251de343e35e11141c49d98b5fcde550e135c3c90aba17cef248b9 729e0101-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=16756 Geološki zavod Slovenije 0 0 0
