dc.description.abstractJatropha (Jatropha curcas L.) seed coat was investigated for removal of Cu (II) from aqueous solutions. Impact of pH of the solution, sorption time, and initial metal ion concentration on sorption capacity was investigated. Adsorption equilibrium was reached in 80 min and 82-89% of Cu (II) was removed by jatropha seed coat at initial Cu (II) concentrations (20-50 mg l⁻¹). Adsorption data, analyzed using Langmuir, Freundlich and Redlich–Peterson isotherms, showed that adsorption equilibrium followed Langmuir and Freundlich isotherms. Kinetics of adsorption followed Elovichian rate equation at 30°C. The most plausible mechanism of adsorption seemed to be electrostatic attraction of Cu (II) towards lignocellulosic polar groups of jatropha seed coat. The study showed that powdered jatropha seed coat can be used as an adsorbent for removal of Cu (II) from wastewater.en_US
