Abstract

In this work waste obtained after extraction of juice from oranges has been evaluated to be used as an adsorbent for removal of textile dye Congo Red. The waste was processed and dried for use. The effect of contact time, pH, and initial concentration of dye was evaluated. Adsorption isotherms were prepared and analyzed to understand mechanism of adsorption. Dye removal was found to decrease with increasing pH. Percent dye removal was found to go down with increase in initial dye concentration. Adsorption isotherms and their analyses revealed that it follows Langmuir pattern.
