Adsorption combined with superconducting high gradient magnetic separation technique used for removal of arsenic and antimony

Submicron fibers as a morphological improvement of amorphous zirconium oxide particles and their utilization in antimonate (Sb(v)) removal

“…[24][25][26] Therefore, several methods for separation of antimony have been suggested including coagulation, liquid extraction, membrane separation, electrochemical methods, adsorption and bioremediation. [27][28][29][30][31][32] For years, antimony separation has been conducted with coagulation method that combines Fe or Al salt precipitation and adsorption. The more common Fe precipitation has effective particularly for Sb(III) but coexisting anions such as PO 4…”

Adsorption performance of antimony by modified iron powder

“…The broad spectroscopy peak located at about 3462.7 cm À1 could be attributed to the O-H bonds stretching resulting from the free water; the bands at 1648.9 cm À1 and 1384 cm À1 may be ascribed to the C-H bonds stretching in the residual acetic acid when the iron powders were modied and the 1004.3 cm À1 peak could be attributed to the C-O in the residual acetic acid or CO 3 2À species. 20,21 The spectroscopy peak at 664.4 cm À1 was likely to result from the Fe-O-H bands and the peaks at 465.7 cm À1 and 587.8 cm À1 could be attributed to the Fe-O-Sb bands, which demonstrated that the Sb(III) or Sb(V) in solution was adsorbed by the iron oxides on the surface of the modied iron powders. 9,13 3.6.3 Schematic process diagram analyses.…”

Adsorption of Inorganic As(III) from Aqueous Solutions by Iron-Manganese Oxide

“…As an effect of arsenic, WHO and USEPA have reinforced guideline value of 10-µg/L 3 . Arsenic poisoning episode in natural ground water has been reported from several countries like Taiwan, West Bengal-India, Chile, Argentina, Mexico, Hungary, Canada, Vitenam, China, USA, Sri Lanka etc 4,5,6 .…”
