Removal of metals from wastewater with titanium dioxide adsorbent
- Resource Consultants, Brentwood, TN (United States)
The treatment of industrial wastewater by adsorption of heavy metals on metal oxides, such as iron oxide or magnesium oxide, has been adopted by some industrial facilities in the last few years. Iron oxide has been successfully employed for wastewater treatment and magnesium oxide for stormwater and other less contaminated wastewaters. The adsorptive properties of some other metal oxides have been evaluated on a laboratory scale. Titanium dioxide is a readily available metal oxide which has received little attention as a potential metal oxide adsorbent for heavy metals. We have investigated the adsorption of lead and cadmium on titanium dioxide. The adsorption of antimony, which exists as an anion in water solution was also investigated. Titanium dioxide was found to be an effective adsorbent for these metals. Interferences by other ions, particularly anions, have been evaluated. The adsorptive properties of titanium dioxide and some potential industrial wastewater treatment applications will be presented.
