Research Abstract |
Experiments to immobilize chromium using the clay minerals such as smectite was conducted. Saponite didn't adsorb chromium ions. However, when using montmorillonite, under the condition pH is 2, chromium was decreased from 1ppm to below the environmental standard value of 0.05ppm. Further, when heated in an air atmosphere 1573K a montmorillonite containing Cr, it was possible to fixate Cr. It was confirmed that it is possible to immobilize intercalated metal ions into clay minerals.
