| Abstract: | The diatomite was surface modified by BaSO4 sedimentation,and the obtained modified diatomite was applied for removal of Pb2+ from simulated wastewater.The batch experiments were conducted to investigate the effect of barium salt concentration,pH,adsorbent dosage,initial Pb2+ concentration and shaking time on Pb2+ adsorption.Finally,the sedimentation performance of modified diatomite and the modification mechanism were discussed.Results showed that the diatomite modified in barium salt solution of 0.20 mol/... |
