Adsorption Studies of Direct Red 28 Dye onto Activated Carbon Prepared from Low Cost Material

Abstract

An experimental investigation on the removal of direct red 28 dye from wastewater by using rice-husk carbon as low cost adsorbent was carried out in a laboratory.

Batch type experiments were conducted to study the influence of different parameters such as adsorbent dose, contact time, pH, initial concentration of dye and particle size of adsorbent. The removal data have been analyzed using Langmuir and Freundlich isotherm models. The adsorption process was in conformity demonstrated use of rice husk to obtain low cost adsorbent for dye removal from aqueous solution .
