The Effect of Sorel's Cement on the Solidification/Stabilization of Heavy Metal Ions
Since the 1980's, many mines have been closed and abandoned due to the exhaustion of deposits and the declining prices of international mineral resources. Because of the lack of post management for these abandoned mines, rivers have been contaminated with heavy metal ions and sludge. We studied the solidification/stabilization of heavy metal ions, chromium ions and lead ions, using Sorel's cement. Specimens prepared by the mixing and reacting of chromium ions and lead ions with Sorel's cement were analyzed by XRD and SEMEDAX to investigate the products and crystal shapes. Furthermore, ICP analysis was used to analyze the content of heavy metal ions in the eruption water from the specimens to check the solidification and stabilization of heavy metal ions. This experiment found that Sorel's cement had excellent solidification effects for chromium ions and lead ions with solidification rates of 99.9% and 99.7%, respectively.
