Sažetak
Mercury capture by natural (NZ) and iron-modified (IMZ) zeolites has been investigated in the batch mode at S/L ratios in the range of 4-140 g/l. The results show that the S/L ratio should not exceed the value of 12 g/l for the IMZ sample. Increased S/L ratio induces increasing amounts of exchangeable cations and pH values in solutions, which may lead to possible precipitation of HgO. At the S/L ratio > 20 g/l, the equilibrium amount of mercury capture (qe) reaches the values of up to 1.8 mg/g for NZ. In case of the IMZ sample, at the S/L ratio < 12 g/l, the value of qe reaches 28.6 mg/g.
