Abstract
ABSTRACT
Dye removal using low cost adsorbent is a suitable method for textile wastewater treatment. The aim of this research work is application of groundnut shell and sorghum husk in powdered form as low cost adsorbent for methylene blue and Congo red dye removal from water at laboratory scale. Batch studies were carried out to determine the adsorption equilibrium of methylene blue and Congo red dye on the two different adsorbent and also to verify the reported data using Langmuir, Freundlich and Temkin isotherm. The study revealed that for the adsorption of methylene blue on sorghum husk, Langmuir Isotherm fitted well the experimental data with R2 value of 0.9710, while for the adsorption of methylene blue on groundnut shell. The Temkin binding energy (bT) are positive for all the experiment, indicating that the process is endothermic. The present work will help to carry out studies in packed column and later scale it up for industrial application.
