dc.description.abstractInorganic arsenic removal from water using low-cost adsorbents is presented in this paper. Selective removal of As(III) and As(V) from water was performed with natural materials (zeolite, bentonite, sepiolite, pyrolusite and limonite) and industrial by-products (waste filter sand as a water treatment residual and blast furnace slag from steel production); all inexpensive and locally available. Kinetic and equilibrium studies were realized using batch system techniques under conditions that are likely to occur in real water treatment systems. The natural zeolite and the industrial by-products were found to be good and inexpensive sorbents for arsenic while bentonite and sepiolite clays showed little affinity towards arsenic. The highest maximum sorption capacities were obtained for natural zeolite, 4.07 mg As(V) g-1, and waste iron slag, 4.04 mg As(V) g-1.en
dc.description.abstractU ovom radu su prikazani rezultati ispitivanja efikasnosti prirodnih i otpadnih materijala za uklanjanje arsena iz vode. Efikasnost uklanjanja arsena, As(III,V) ispitana je u šaržnom sistemu. Kao sorbenti korišćeni su prirodni materijali (zeolit, bentonit, sepiolit, piroluzit i limonit) i otpadni materijali (otpadni filtarski pesak sa postrojenja za prečišćavanje voda i otpadna šljaka iz proizvodnje čelika). Ispitivanja su pokazala da otpadni materijali mogu efikasno ukloniti i As(III) i As(V) iz vode, ali da se efikasnost razlikuje i zavisi od valentnog stanja arsena, početne koncentracije i pH vrednosti vode. Eksperimenti na osnovu kojih su dobijene krive kinetike sorpcije i sorpcione izoterme su rađeni u uslovima kakvi vladaju u realnim sistemima za prečišćavanje vode. Prirodni zeolit o otpadni materijali su se pokazali kao relativno dobri materijali za uklanjanje arsena iz vode dok su bentonit, sepiolit, limonit i piroluzit pokazali slab afinitet prema arsenu. Najveći maksimalni sorpcioni kapacitet su pokazali prirodni zeolit (4,07 mgAs(V) g-1), i otpadna šljaka (4,04 mgAs(V) g-1).sr
