dc.description.abstract | Cement based solidification/stabilization technology has been widely practiced for the treatment of inorganic hazardous wastes, especially metal-bearing wastes. The advantage of using the solidification/stabilization process is that the mobility of the hazardous materials is greatly retarded in the final disposal sites. The purpose of this study is to assess the stability of a synthetic solid waste through the renewable leaching test. A major cement constituent, dicalcium silicate (C2S), was used as a model binder to react with copper oxide to form a solid waste matrix. The semi-dynamic leaching test using 1 N acetic acid was employed to investigate the leaching characteristics of the C2S/CuO system. The results show that the dissolution of Ca(OH)2 is the primary mechanism for the destruction of the matrix, and the subsequent leaching of copper ion. The surface-controlled dissolution reaction increases the pore size and porosity of the matrix, thus increasing the diffusion rate of copper ion transport. The C2S hydration product, silicate hydrate, might play a role in adsorbing the copper ion in the leaching system. © 1994, Taylor & Francis Group, LLC. All rights reserved. | - |
