Reduction of oxoselenium anions by iron(II) hydroxide

摘要

the reaction between iron(II) hydroxide and solutions containing oxoselenium anions results in a dramatic reduction in the concentrations of dissolved selenate and/or selenite. This reaction presents the possibility of a practical method for the removal of soluble selenium from water systems. Examination of the iron precipitates which carry the selenium was carried out. Basic chemical Reactions to isolate the selenium followed by x-ray photoelectron spectroscopy, powder x-ray Diffraction, energy dispersive spectroscopy, transmission electron microscopy, a electron Diffraction patterns establish the identity of the selenium products as the element in its stable gray, Trigonal form.
