Author(s): D. Abilasha, L. Lisy
Abstract: The present study was focused on the variety of Heva Brasiliensis seed coat, as an alternative adsorbent for the removal of Cu (II) and Zn (II) ions from aqueous phase. Both adsorption experiments were conducted by using Hevea Bresiliensis seed coat charcoal. Batch adsorption study used 100 ml solution containing heavy metals ion of varying concentration shaking and filtering were carried prior to measuring final residual heavy metals remaining in solution. Batch experiments were conducted at room temperature 30°C to determine the factors affecting adsorption of Cu (II) and Zn (II) ions. The adsorption process is affected by various parameters such as contact time, solution pH, adsorbent does and initial concentration. The experimental data was tested using Langmuir and freundlich equations. The data was fitted well to both Langmuir and freundlich isotherms. The data was fitted Hevea Bresiliensis seed coat activated carbon charcoal could be used as low cost adsorbents and easily available in larger quantities especially for the removal of metal ions such as Cu2+and Zn2+ ions.
