Abstract: |
With oscillating adsorption experiment, the effects of pH, contact time, temperature, Pb2+ initial concentration and doses of adsorbent were evaluated. It was revealed that the removal rate of Pb2+ in modified titanium dioxide could be reached to 92% under the following condition: pH 5.0±0.1, contact time 120min, temperature 293K, Pb2+ initial concentration 100mg/L, amount of adsorbent 80mg/L. The adsorption capacity was 32.89mg/g.
