Preparation and Adsorption Study of Gelatin/Activated Carbon Composite Bead Form

Abstract:

The aim of this work is to prepare the Gelatin/Activated Carbon (GE/AC) composites in bead form using for adsorption of Rhodamine B. The scanning electron microscope (SEM) shows smooth surface and pore distribution for an external and internal GE/AC composite bead, respectively. FTIR-ATR spectra indicate the presence of AC on the GE/AC bead surface. It was found that an increase in the AC content in GE solution from 0.5 to 2.5 wt% resulted in an increase in the percentages of dye adsorption of GE/AC bead from 13.79 to 52.87%. Under the study of equilibrium isotherm it was found that the adsorption isotherm of Rhodamine B follows Langmuir isotherm model. The results indicate that GE/AC adsorbent could be employed for removal of cationic dyes from textile effluent.
