Abstract
Wastewaters obtained from fenvalerate manufacturing process were treated for its safe disposal using activated coconut shell carbon (acc) as adsorbent. In this work, the removal efficiency of organic matter in terms of chemical oxygen demand (COD) utilizing acc has been investigated. Various parameters which can influence the adsorption like adsorbent dosage, contact time of solution with adsorbent and pH were optimized. Isotherms for adsorption were developed and the equilibrium data was fitted in to linearized equation of Langmiur and Freundlich isotherms models.
