Abstract

Adsorption of dye on clay and its thermal studies

Author(s):Tanushree Choudhury, N.M.Misra

Dyes are flat polyaromatic molecules that bind selectively to the clay surface over a wide a wide pH range. Dyes are generally hydrophobic in nature and generally adsorb in aggregates at the flat silica faces of clay mineral which is made hydrophobic by cation exchange process. The present work involves use of natural turmeric dye which is adsorbed on clay surface. The role of the resulting hybrid material as potential indicator is studied for the development of biosensor. The thermal stability is studied usingDSC. Binding of clay and dye is studied using FTIR. Morphological structure of the hybrid material is studied using SEM.
