dc.description.abstractU radu su prikazani rezultati adsorpcije uranil jona na modifikovanim prirodnim zeolitima: HZ – zeolitu koji je modifikovan hidronijum jonima i OHZ – zeolitu ~ija je povr{ina modifikovana primarnim aminom – stearil aminom. U odnosu na prirodni zeolit, oba modifikovana zeolita pokazuju visok indeks adsorpcije uranil jona. Dobijeni rezultati su ukazali da pri masenom odnosu adsorbent: uranil jon 1000:1, indeks adsorpcije uranil jona na uzorku HZ iznosi 95.3 posto, a na uzorku OHZ 99.9 posto. Smanjenje masenog odnosa adsorbent: uranil jon, dovodi do opadanja indeksa adsorpcije uranil jona kod oba modifikovana zeolita. Tako, pri masenom odnosu adsorbent: uranil jon 50:1, dobijeni su indeksi adsorpcije: HZ – 42 posto, OHZ – 56.5 posto.sr
dc.description.abstractThe results of adsorption of uranyl ion on modified natural zeolites: HZ – zeolite modified with hydronium ions and OHZ – zeolite whose surface was modified with primary ammine, are presented in this paper. Compared to unmodified zeolite, both modified samples showed high uranyl ion adsorption indexes. The obtained results showed that, at mass ratio adsorbent: uranyl ion 1000:1, the uranyl ion adsorption index was 95.3% on sample HZ and 99.9% on sample OHZ. On both modified zeolites, a general trend of decreasing uranyl ion adsorption with decreasing the mass ratio adsorbent: uranyl ion can be observed. At mass ratio adsorbent: uranyl ion 50:1, the following adsorption indexes were obtained: 42% on sample HZ and 52% on sample OHZ.en
