Abstract
Utjecaj omjera kruto tekuće, S/L na sorpciju Hg(II) iz vodene otopine ispitan je na prirodnom i Fe(III)-modificiranom zeolitu. Sorpcija je provedena pri optimalnom pH o =1,98 te S/L = 2 – 80 g/L na prirodnom zeolitu i S/L = 2 – 36 g/L na Fe(III)-modificiranom zeolitu. Rezultati su pokazali da je optimalno S/L područje za sorpciju Hg(II) ≤ 30 g/L za prirodni zeolit te ≤ 14 g/L za Fe(III)-modificirani zeolit. Ravnotežne koncentracije Hg(II) i količine sorbirane Hg(II) na uzorcima zeolita smanjuju se porastom S/L omjera. Maksimalna učinkovitost sorpcije od 73,92% postignuta je pri S/L = 30 g/L na prirodnom zeolitu te 86,45% na Fe(III)-modificiranom zeolitu pri S/L = 14 g/L što ga izdvaja boljim sorbentom za sorpciju Hg(II).
Abstract (english)
The effect of the solid-liquid, S/L ratio on the sorption of Hg(II) from aqueous solution was investigated on natural and Fe(III)-modified zeolite. Sorption was performed at optimal pH o = 1.98 and S/L = 2 - 80 g/L onto natural zeolite and S/L = 2 - 36 g/L onto Fe(III)-modified zeolite. The results showed that the optimal S/L range for Hg(II) sorption is ≤ 30 g/L for natural zeolite and ≤ 14 g/L for Fe(III)-modified zeolite. Equilibrium concentrations of Hg(II) and the amount of sorbed Hg(II) on zeolite samples decreases with increasing in S/L ratio. The maximum sorption efficiency of 73,92% was achieved at S/L = 30 g/L for natural zeolite and 86.45% for Fe(III)-modified zeolite at S/L = 14 g/L, which highlights Fe(III)-modified zeolite as the better sorbent for Hg (II) sorption.
