| Abstract | U ovom radu je ispitana mogućnost primjene prirodnog zeolita, Fe(III)-modificiranog zeolita, kaolina, bentonita, apatita i koncentriranog apatita kao potencijalnih materijala za permeabilnu reaktivnu barijeru za uklanjanje iona bakra iz onečišćenih podzemnih voda. Šaržnim postupkom provedeno je zasićivanje sorbenata s ionima bakra te desorpcija iona bakra iz zasićenih sorbenata u otopinama ultračiste vode pH vrijednosti 2,94 i 6,46. Rezultati ukazuju na sljedeći red selektivnosti sorbenata prema ionima bakra: bentonit > FeZ > PZ > konc. apatit > apatit > kaolin. Izračunati koeficijenti raspodijele i koeficijenti zadržavanja na ispitivanim sorbentima potvrdili su rezultate sorpcijskih eksperimenata. Utvrđeno je da svi ispitivani sorbenti nisu potencijalni materijali za PRB pri pH vrijednosti medija ispod pH=3, jer dolazi do desorpcije iona bakra. Pri slabo kiselim i neutralnim uvjetima bentonit je potencijalni materijal za PRB budući je pokazao najveću selektivnost prema ionima bakra i ne dolazi do njihove desorpcije. |

| Parallel abstract (English) | In this paper the possibility of application of natural zeolite, Fe(III)-modified zeolite, kaolin, bentonite, apatite and concentrated apatite as potentials materials for the permeable reactive barrier for copper removal from contaminated groundwater has been investigated. Saturation of sorbents with copper ions and desorption of copper ions from saturated sorbates in ultrapure water solutions at pH 2.94 and 6.46 has been performed by the batch process. The results indicate the following sequence selectivity of sorbent toward copper ions: bentonite > FeZ > PZ> conc. apatite > apatite > kaolin. Calculated distribution coefficients and retention coefficients on the investigated sorbents confirmed the results of sorption experiments. It has been found that all tested sorbents are not potential materials for PRB below pH=3 due to desorption of copper ions. At weak acidic and neutral conditions, bentonite represent potential PRB materials since it showed the highest selectivity to copper ions and its desorption did not occur. |
