Abstract

La invencion describe un metodo para secuestrar oxidos de arsenico, que comprende formar un vidrio insoluble y estable incorporando una forma completamente oxidada de arsenico generada por oxidacion de un oxido inferior de arsenico inicial y su estabilizacion por formacion de una sal de calcio. La composicion de vidrio para secuestrar arsenico comprende entre 50 y 75% de silice; entre 0,5 y 3% de Al2O3; entre 1 y 15% de MnO; entre 5 y 15 % de CaO; entre 1 y 20% de As2O5 y entre 8 y 14% de Na2O, y menos del cuatro por ciento de oxidos de hierro, oxido de magnesio y otros oxidos
