Abstract

This investigation was to evaluate the adsorption capability of activated carbon prepared from Thevetia Peruviana wood for removal of reactive
textile dye (RO4) from aqueous solution. Batch adsorption experiments were performed as a function of initial dye concentration, contact time,
temperature and pH. The amount of dye adsorbed increased while increasing the initial concentration and temperature of the solution. The
experimental data fitted well to Pseudo second order kinetic model with Intra particle diffusion as the rate determining step. Adsorption data fitted
with Langmuir model. The negative value of Gibb’s free energy (∆G°) indicated that the adsorption was spontaneous in nature. The results showed
that the activated carbon of Thevetia Peruviana was suitable for the removal of the reactive dyes from the aqueous solutions. The positive value of
enthalpy (∆H° ) indicated that the adsorption of the selected dyes were endothermic.

Keywords: Activated Carbon, Adsorption, Dyes, Reactive Orange4.
