Abstract	Prirodni zeolit klinoptilolit je kemijski modificiran s otopinom Na 2 S pri 150 °C. Ispitana su sorpcijska svojstva polaznog uzorka, prirodnog zeolita klinoptilolita te dobivenog sumporom- impregniranog prirodnog zeolita prema ionima Hg(II) pri unaprijed definiranim optimalnim uvjetima, pH o =2 i omjeru kruto/tekuće 10 g/L. Maksimalni dobiveni kapacitet sorpcije sumporom-impregniranog prirodnog zeolita prema Hg(II) iznosi 1,02 mmol/g što je za 3,6 puta više u usporedbi s prirodnim zeolitom (0,28 mmol/g). Sorpcijski mehanizam Hg(II) na sumporom-impregniranom prirodnom zeolitu uključuje elektrostatsko privlačenje, ionsku izmjenu i površinsko kompleksiranje uz koprecipitaciju Hg(II) u obliku HgS što je potvrđeno određivanjem količine izmjenjivih zeolitnih kationa kao i SEM- EDS i TG-DTG analizom živom zasićenog sumporom-impregniranog prirodnog zeolita.
Abstract (english)	Natural zeolite clinoptilolite is chemically modified with Na 2 S solution at 150 °C. The sorption properties of the initial sample, natural zeolite clinoptilolite and the obtained sulphur- impregnated natural zeolite towards Hg(II) ions were tested under pre-defined optimal conditions, pH o =2 and a solid/liquid ratio of 10 g/L. The maximum obtained sorption capacity of sulphur-impregnated natural zeolite towards Hg(II) was 1.02 mmol/g, which is 3.6 times more compared to natural zeolite (0.28 mmol/g). The sorption mechanism of Hg(II) on sulphur-impregnated natural zeolite includes electrostatic attraction, ion exchange and surface complexation with coprecipitation of Hg(II) in the form of HgS, which was confirmed by determining the amount of exchangeable zeolite cations as well as SEM-EDS and TG-DTG analysis of mercury saturated sulphur-impregnated natural zeolite.
