5.3 RESULTS
5.3.1 pH evolution
During the experiments, the pH of the leachates shifted from the pre-set value to higher pH
values due to neutralization potential of the slags. The pH change varied depending on slag
and solution used (Figures 5.2-5.4). A more significant neutralization of pH occurred in case
of GS and SFS, whereas HS and LS revealed slightly acidic pH.
5.3.2 Metal release
The concentrations of metals in the leachates (24, 48, 72, 168 and 960 hours) are plotted as a
function of final solution pH (Figures 5.2-5.4) and data from the individual sampling points is
presented in Table 5.2.
