摘要：
Lepidocrocite (gamma-FeOOH) nanoflakes were synthesized using a simple ethylene glycol (EG) mediated solution method. The obtained gamma-FeOOH were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and nitrogen adsorption-desorption isotherms. The absoption properties of the as-prepared gamma-FeOOH nanoflakes towards toxic As(V) and Cr(VI) ions were investigated. The effects of anions such as Cl-, SO42-, NO3-, HCO3-, CO32-, and PO43- on As(V) removal were also investigated. The results indicated that phosphate was the greatest competitor with As(V) for adsorptive sites. The presence of Cl-, SO42-, and NO3- had no effect on As(V) removal.
