Leaching of Incinerator Slag from Municipal Waste

摘要

A leaching study was performed on monoliths obtained by melting iron-rich municipal waste frit. The leachant was distilled water at 363 exp 0 K. For tests where the leachant was intermittently changed and the specimens weighed, leach rates on the order of 1 x 10 exp -4 g.cm exp -2 d exp -1 were observed. For tests where the samples remained in the unperturbed leachant for the duration, leach rates were on the order of 3 x 10 exp -5 g.cm exp -2 d exp -1 . These leach rates are similar to those obtained for other solidified waste forms, and are lower than those reported for concrete. (ERA citation 05:006556)
