Abstract
In this paper, nanometer titanium dioxide was synthesized by a simple reaction. The prepared adsorbent was characterized by surface area and porosimetry analyzer and it was used for the removal of heave metals in industrial wastewater. The main parameters affecting the adsorption of heavy metals including pH, adsorption condition and elution condition have been investigated in detail. Under the optimized operating conditions, most of the target heavy metals could be fast removed. The adsorbent could be simply regenerated by hydrochloric acid. Thus, the prepared nanometer titanium dioxide was an adsorbent which is suitable for the removal of heavy metals in industrial wastewater.
