摘要：

The influence of the binder/waste ratio (AG/WS) on the leaching characteristics of two solidified/stabilized (S/S) steel foundry dusts has been investigated. Leach testing of the solidified products using the Toxic Characterization Leaching Procedure was used to determine the levels of Cd, Pb, Cr and Zn in leachates. The results show that the waste/binder ratio significantly influence the ability of solidified dusts to pass US EPA regulations. For the two wastes investigated minimum waste/binder ratios of 0.37 and 0.25 are recommended for CSFD and SSFD dusts, respectively.
