Adsorption of solophenyl red 3BL polyazo dye onto amine-functionalized mesoporous carbons.

Mesoporous carbon of cubic structure was functionalized with ethylamine, ethylenediamine, diethylenetriamine and triethylenetetramine at 40°C for 8h. The mesostructure and textural parameters of the new materials were determined by X-ray diffraction and low-temperature nitrogen sorption techniques. The functional groups present on the surface of the samples were identified by FT-IR and thermogravimetric studies.
