The present study was undertaken to compare the adsorption efficiency of removal of refractory
organic compound which is responsible for refractory COD from petrochemical industrial waste
water form agro based activated carbon prepared from banana tree root residue, teak wood saw
dust and commercial available activated carbon (180 & 120 MB value).Activated carbon
prepared by impregnation with ZnCl2 and carbonization at 600ºC.Adsorption capacity has been
tested for de-colourisation of aqueous solution contain Methylene blue. The experimental
examinations of adsorption were carried out with various contact time and various doses of
activated carbon to determination of optimum dose and effective time to removal of Refractory
COD. The agro based activated (banana tree root residue give 8.76 % removal efficiency at 8.5
gram dose with 50 min contact time and Teak wood saw dust activated carbon achieved 23.96%
removal efficiency at 7.5 gram dose with 50 min contact time. The optimum dose of 180 & 120
MB Value Commercial available activated carbon was 7 and 17 with 50 min effective contact
time and COD removal efficiency was 36.19% & 21.96 % respectively.
