Abstract

Clay from Ikpoba in Benin city was tested as lowcost adsorbents for Cu(II) and Pb(II) removal from aqueous solutions. A full factorial experimental design was utilized to assess the effect of four factors on the batch adsorption of Cu(II) and Pb(II) with the clay (particle size < 0.02mm). The chosen experimental factors were adsorbent dose, temperature, shaking speed, and contact time. The results indicated that only adsorbent dose had significant effect for both ions. The best conditions for uptake of ions were respectively time of 90 minutes and 60 at 0.2g adsorbent.
