Abstract

Kinetics adsorption of lead from aqueous solution using silica ceramic has been investigated in batch methods. The
effect of solution pH, initial metal ion concentration, temperature and adsorbent mass on metal ion removal has been
studied. The process of lead adsorption follows pseudo second-order rate expression and obeys the Langmuir’s model
with high correlation coefficient (R2>0.99) and better than other equations. The maximum removal achieves 2.7 mg/g.
The result indicates that under the optimum conditions, the maximum adsorption value for Pb(II) comply the silica
ceramic is a potential adsorbent for Pb(II).
