Abstract
Abstract
Antimony oxide was synthesized by a simple method involving the mixing of
6 M HCl and antimony pentachloride, adjusting the synthesis pH with
25% ammonia. The obtained material was characterized using X-ray
diffraction, field emission scanning electron microscopy, and surface area and
pore size analysis. The material structure resembled that of
Sb6O13. The cobalt sorption efficiency of the synthesized antimony
oxide was tested in the dark and under UV-C irradiation. The 0.01 M
NaNO3 test solution contained varying concentrations of Co2+ and
EDTA and was traced with 57Co. The cobalt concentration in the
solutions was determined by gamma spectroscopy. The synthesized material
proved to have a high cobalt uptake. In the presence of 20 μM EDTA, 99.7% of cobalt was removed from the solution after
2 h of UV-C irradiation.
