Abstract
Arsenic species in alkaline extracts of sulfidic and arsenic slags as well as in water in mines were analyzed by ion chromatography and capi llary zone electrophoresis. The total arsenic was determined in both k inds of samples by FIA-hydride AAS, in the slags after microwave induc ed 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.
