Abstract
A process was developed in which flouroarsenate and/or flouroantimonate ions are precipitated by quaternary phosphonium or ammonium compounds acting as precipitating agent from solutions containing arsenic and/or antimony in the form of flourine complexes. This method can be coupled with a conventional method of precipitating arsenic and/or antimony oxo anions.
