Arsenic is a by-product of many metallurgical operations and its contribution to environmental pollution is of major concern. Various techniques for removing arsenic from plant liquors and effluents have been suggested in the literature. This paper summarises results on the removal of arsenic as ferric arsenate which were obtained in three independent laboratories (National Technical University of Athens, Greece, the Technical University of Košice, Slovakia and the University of Chemical Technology, Burgas, Bulgaria). Aspects of the molar ratio Fe/As, pH, temperature, initial concentration of arsenic, reagent addition sequence and the stability of ferric arsenate precipitates are dealt with in this paper. (EN)
