Abstract
Utjecaj pH na sorpciju Hg(II) iz vodene otopine ispitan je na prirodnom i Fe(III)-modificiranom zeolitu. Sorpcija je provedena pri pH 2,09 i 2,30. Rezultati su pokazali da je optimalni pH = 2,09 dok je pri pH = 2,30 došlo do taloženja Hg(II) u suspenziji. Ralog tome su veće ravnotežne pH vrijednosti od izračunate pH vrijednosti od 2,45 pri kojoj dolazi do taloženja za početnu koncentraciju od 4,006 mmol Hg/L. Količina sorbirane Hg(II) na Fe(III)-modificiranom zeolitu je za 1,4 puta veća u odnosu na prirodnom zeolitu, dok je postignuta učinkovitost sorpcije Hg(II) 81% na Fe(III)-modificiranom zeolitu te 57% na prirodnom zeolitu.
Abstract (english)
The effect of pH on the sorption of Hg (II) from aqueous solution was investigated on natural and Fe (III)-modified zeolite. Sorption was performed at pH 2.09 and 2.30. The results showed that the optimal pH is 2.09 while at pH = 2.30 precipitation of Hg (II) occurred in suspension. The reason for that are higher equilibrium pH values than the calculated pH value of 2.45 at which precipitation occurred for an initial concentration of 4.006 mmol Hg/L. The amount of sorbed Hg (II) onto Fe (III)-modified zeolite is 1.4 times higher than that natural zeolite, while the achieved sorption efficiency of Hg(II) is 81% on Fe (III)-modified zeolite and 57% on natural zeolite.
