Abstract

The attempt of this study was to use rubber wood ash (RWA), an agricultural waste, as an adsorbent for the adsorption of Ni(II) and Cu(II) ions from aqueous solution. The average particle size of RWA was 35.4 μm. The BET surface area was 42 m2/g. SEM of RWA reveals it very fine particle size to the order of millimeter or less and that there are pores of varying sizes within the particle. The diffraction pattern confirms the CaO is the main content in RWA. Studies were carried out on the function of rotation speed, amount of dosage and contact times. RWA was found to be an effective adsorbent for the removal of 99.86% for nickel (Ni(II)) and 99.44% for copper (Cu(II)) metal ions from aqueous solutions. Optimum conditions for Ni(II) and Cu(II) ions removal were found to be adsorbent dosage of 10 g/l, 20 minutes equilibrium time and rotation speed of 400 rpm. The results suggest that RWA can be used as an adsorbent for an efficient removal of metal ions from aqueous solutions.
