Abstract
U ovom radu je ispitano izluživanje elemenata iz nepropisno odloženog otpada u naselju Štrmac, koji je nastao industrijom ugljena. Sakupljena su 4 uzorka na 2 lokacije unutar odlagališta. Na svakom uzorku su provedene 2 metode ekstrakcije, ASTM i TCLP (pH 2,9). Uzorci su potom podvrgnuti sekvencijskom filtriranju kako bi se dobile 4 različite veličinske frakcije. Korišteni su acetatno-celulozni filteri s veličinom pora 0,45, 0,22 i 0,10 μm kao i ultracentrifugalni filter (Amicon Ultra-15) s veličinom pora otprilike 0,008 μm. Na dobivenim eluatima je provedena multielementna analiza primjenom tehnike spektrometrije masa visoke razlučivosti uz induktivno spregnutu plazmu (HR-ICP-MS). U svim uzorcima analizirane su koncentracije 15 elemenata (Li, Mo, Pb, U, Al, V, Cd, Mn, Fe, Co, Ni, Cu, Y, As i Se). Rezultati pokazuju da, osim pH i mineralogije, postoje dodatni čimbenici koji utječu na izluživanje elemenata i olakšavaju njihov prijenos što predstavlja prijetnju za okoliš.
Abstract (english)
Leaching of elements from unregulated waste located in Štrmac village is studied in this thesis. Said waste is a byproduct generated by coal industry of that area. Four samples were collected from 2 locations within the dumpsite. Each sample was subjected to 2 extraction methods, ASTM and TCLP (pH 2,9). Samples were then filtrated to obtain 4 different size fractions. Cellulose acetate filters with pore size 0.45, 0.22 and 0.10 μm were used as well as ultra centrifugal filter (Amicon Ultra-15) with pore size approximately 0.008 μm. Multielemental analysis was performed on obtained eluates using HR-ICP-MS. All samples were analysed for concentrations of 15 elements (Li, Mo, Pb, U, Al, V, Cd, Mn, Fe, Co, Ni, Cu, Y, As and Se). Results show that additional factors, besides pH and mineralogy, can effect leaching of elements and facilitate their transport which presents threat to the environment.
