Production of Adsorption Materials from Bentonite Clay Containing an Organic Dye

详细

Carbon-containing materials were produced from a mixture of bentonite clay and Crystal Violet dye adsorbed on the clay. X-ray diffraction analysis and IR spectroscopy were used to examine the thermal and structural transformations occurring in a thermal treatment of a mixture of the clay and the adsorbed dye in the atmosphere of water steam, and the optimal carbonization conditions were determined. It was shown that the materials possess a high adsorption capacity for basic organic dyes.
