Chromium (III) Immobilization and Its Influence on Hydration
Publication: Practice Periodical of Hazardous, Toxic, and Radioactive Waste Management
Volume 14, Issue 4
Abstract
The hydration characteristics of were studied in the presence of chromium (III) for up to 7 days. Chromium was introduced by either direct incorporation (as ) during preparation or during the subsequent hydration with a chromium solution. Levels of Cr(III) used were 1 and 3% by wt. of . The chemically combined water content and free lime content were determined after 3 and 6 h and 1, 3, and 7 days of hydration. The results showed a retardation effect for the hydration of in the presence of Cr, especially during the first hours of hydration. This retardation effect was more evident in incorporated mixes than in mixes hydrated in Cr-containing solutions. X-ray diffraction examination was performed on selected samples. The immobilization percentage of Cr(III) by during hydration was determination by atomic absorption spectroscopy. A high degree of Cr immobilization (93.27–99.39%) was found after 7 days of hydration.
