Abstract

Cadmium, a carcinogen creates Itai-itai disease, renal damage, emphysema, hypertension and testicular atrophy. The present study focus on adsorptive removal of Cd(II) ions from aqueous solution using coffee powder, which was carried out under optimum conditions of pH, temperature, biosorbent dosage, initial ionic concentration and contact time. The Cd(II) ions adsorption on coffee powder was about99.5% at pH3.5 in 60 minutes. The adsorption of Cd(II) ions in coffee powder follows both Langmuir and Freundlich adsorption isotherms.
