Dyes are principal pollutants from the industries like textile, fabric etc in water which need treatment. In this study, activated carbon was taken from vehicular exhausts. The experiments were carried out to explore Malachite Green & Methyl Orange uptake by carbonised matter. The effect of experimental factors such as adsorbent dosage & contact time was investigated by using 10 ppm of the dye solution. The adsorption equilibrium was represented by Langmuir adsorption isotherms. Adsorption of Malachite Green & Methyl Orange onto vehicle carbonised matter followed pseudo first order kinetics.
