In recent years, many researchers uses various natural adsorbent for the removal of heavy metals from the industrial waste water. The heavy metals from the effluents discharge in aqueous stream causes a great hazard to the environment. Adsorption method is the effective technique for the removal of heavy metals from the aqueous solution even in very low concentration. The present adsorption study focuses to evaluate the potential of chemically activated Couropita guianensis carbon for the removal of Copper (II) ions in the aqueous solution. The chemically activated carbon was characterized using standard American Standard Testing Methods. (ASTM). Morphology of carbon particles have been characterized using Scanning Electron Microscopy (SEM). Adsorption studies performed by batch experiments showed that the adsorbent prepared from fruit of Coroupita guianensis has good capacity of copper ions adsorption from aqueous solution The preparation and characterization of activated carbon are listed out and well prepared porous activated carbon was studied under various parameters include contact time, adsorbent dosage, initial concentration, pH. The adsorption process of copper (II) is tested with Langmuir and Freundlich adsorption isotherm models.
