Abstract
Arsen je dobro poznat metaloid koji uzrokuje ozbiljne probleme u vodi za piće budući da je iznimno otrovan. Prisutnost arsena u podzemnim vodama je posljedica otapanja minerala u zemljinoj kori ili ispiranja spojeva arsena rastapanjem metalnih ruda, poljoprivrednih pesticida ili sredstava za zaštitu šuma. Povišene koncentracije arsena u vodi utvrđene su i u bunarskim vodama Istočne Hrvatske. Za uklanjanje arsena iz vode za piće primjenjuju se različite metode koje se baziraju na različitim fizikalno kemijskim postupcima. Budući da se jednostavno uklanja kruti sorbens iz vodenog medija nakon obrade, sorpcija se uglavnom smatra da je najbolja odgovarajuća metoda. Procesi sorpcije pomoću prirodnih zeolita vrlo su poželjni, jer oni zahtijevaju blage uvjete djelovanja i nisu toksični. Cilj ovog rada bio je odrediti učinak uklanjanja arsena ovisno o promjeni mase adsorbensa , temperaturi i pH vrijednosti na dvije vrste modificiranog prirodnog zeolita. Prirodni zeoliti sa klinoptilolitom kao glavnom mineralnom komponentom, koji su korišteni u ovom radu, potječu iz ležišta Donje Jesenje, Hrvatska i Vranjska Banja, Srbija.

Arsenic is a well-known metalloid, which causes serious health problems. The presence of arsenic in groundwater is due to the dissolution of minerals in the earth’s crust or the leaching of arsenic compounds from smelting of metal ores, agricultural pesticides or wood preservatives. Appearance of high arsenic concentrations is usual for the groundwaters in eastern Croatia. Few technologies based on different physical-chemical procedures have been developed for arsenic removal from drinking water, and sorption is one of generally considered suitable methods for contaminated waters. The sorption processes by natural zeolite are very attractive, since they require mild operating conditions and are non-toxic. The aim of this work was determination arsenic removal efficiency depending on change of mass adsorbent, temperature, and pH values of two species natural modified zeolite. Natural zeolite samples with clinoptilolite used this work obtained from two deposits, Donje Jesenje, Croatia and Zlatokop deposit in Vranjska Banja, Serbia.
