Zur Analytik von Oxothioarsen‐Species in Schlacken und Grubenwässern

Analysis of Oxothio Arsenic Species in Soil and Water Arsenic species in alkaline extracts of sulfidic and arsenic slags as well as in water in mines were analyzed by ion chromatography and capillary zone electrophoresis. The total arsenic was determined in both kinds of samples by FIA‐hydride AAS, in the slags after microwave induced pressure digestion, and in the untreated solid samples also by RFA. Arsenate, arsenite and monothioarsenate ions could be identified and quantified as stable arsenic species.
