    Double filtration an efficient method to treat arsenic ...

     · Arsenic is usually present in water in two oxidation states, as arsenite (As(III)) or arsenate (As(V)). Arsenate is usually easier to remove than arsenite. Therefore, the goal of this study is to check the potential use of double filtration for improving As(III) removal and to investigate if something happens with membrane, with arsenic solution, or both, after first filtration of As(III).

    Chromatographic separation of germanium and arsenic for ...

     · The separation of arsenic from germanium was based on their relative affinities for different chromatographic materials in aqueous and organic environments. Using an organic or mixed mobile phase, germanium was selectively retained on a silica gel column as germanate, while arsenic was eluted from the column as arsenate.

    The separation of arsenic from copper in a Northparkes ...

     · In order for the higharsenic regions of the Northparkes copper–gold orebody to be beneficiated economically, tennantite ((Cu,Fe) 12 As 4 S 13) present in the ore needs to be rejected to enable copper concentrates to meet the typical smelter penalty level of 2000 ppm As. Using a composite sample of higharsenic drill cores from Northparkes it was possible to selectively separate tennantite ...

    The comparison of arsenic capture by ferrospheres and fly ashes was made experimentally in a simulated flue gas at 873 K. Results show the Feenriched ferrospheres can achieve a higher removal efficiency of % in this study, which is almost twice that of the raw ashes. With the temperature increasing from 573 to 1073 K, the arsenic capture ...
