| Abstract |
Sorption is one of the important fixation mechanisms of metals in stabilized/solidified waste forms. In the present work, the sorption-desorption processes active in cement-based waste forms in acetic acid solutions were investigated. Experimental results indicated that the extent of sorption of a metal ion was strongly pH dependent. Cement-based waste forms had similar sorption characteristics as amphorous silica gel. The pH of the sorption edge is 5 to 6.5 for Pb(2+) and As(3+), 6 to 8.5 for Cd(2+), and 8 to 12 for Ca(2+). In addition, almost 90% of the lead and cadmium were leachable at pH 4.5, while nearly 30% of arsenic remained unleached at the same pH.
