Sorption of antimony and arsenic from aqueous solutions by inorganic sorbents
This paper reports a study of the sorptive properties of nonferrous metal sulfides, natural manganese dioxide (pyrolusite), and activated semicoke (low-temperature coke) in antimony and arsenic solutions. It was found that maximum sorption of arsenic and antimony compounds by sulfides occurs in the pH range 6.2-7.0. The limiting capacity of pyrrhotite to pentavalent arsenic is 0.82, and to trivalent arsenic 0.74 mmole/g. The sulfides can be ranked in decreasing order of limiting capacity: FeS-PbS-ZnS-..beta..-CdS-Cu/sub 1.97/S. It has been shown that the limiting capacity of pyrolusite for antimony is 0.209 mmole/g, which makes it possible to recommend manganese dioxide as an inorganic sorbent for the purification of mine waters from compounds of antimony and arsenic.
