Fixed-Bed Adsorption of Dyes on Bagasse Pith

Abstract

The adsorption of a number of basic dyes on to bagasse pith has been studied using fixed-bed adsorption. Pith is a waste material produced from the crushed cane (depithing operation) during the extraction of sugar from sugar cane. The results show that pith can adsorb basic dyes and breakthrough curves are reported at various heights in the fixed beds. The bed depth service time model has been used to assess the results.
