摘要: Vanadium is listed on the United States Environment Protection Agency (USEPA) candidate contaminant list # 2 (CCL2), and regulatory guidelines for vanadium exist in some US states. The USEPA requires treatability studies before making decisions CCL2 contaminants. Previous have examined adsorption onto metal hydroxides but not commercially available adsorbents. This paper briefly summarizes known occurrence North American groundwater assesses removal by three oxide adsorbents with different mineralogies. GTO (Dow) TiO2 based E-33 (Seven Trents) GFH (US Filter) are iron based. Preliminary vanadate kinetics GFH, has been studied homogenous surface diffusion model (HSDM) used to describe data. effects of pH, concentration, volume/mass ratio assessed. decreases increasing maximum capacities achieved at pH 3-4. Results indicate that all remove vanadium; highest capacity, followed E-33. Data best fit Langmuir rather than Freundlich isotherms. Both sorption maxima (Xm) binding energy constant (b) follow trend GFH>GTO>E-33. Naturally occurring also removed from Arizona ground water rapid small-scale column tests (RSSCTs). Metal technologies currently arsenic may always same effectiveness.
