Abstract

SE REFIERE A UN PROCESO QUE CONSISTE EN OXIDAR EL ARSENICO A ARSENICO PENTAVALENTE EN UN MEDIO ACUOSO MEDIANTE EL USO DE BACTERIAS OXIDANTES A UN pH ENTRE 0,5 Y 4 A UNA TEMPERATURA ENTRE 20°C Y 85°C EN PRESENCIA DE UN CATALIZADOR MINERAL QUE CONTIENE AZUFRE, Y SUMINISTRAR HIERRO TRIVALENTE QUE SE PONDRA EN CONTACTO CON EL ARSENICO PENTAVALENTE PARA FORMAR UN COMPUESTO INSOLUBLE DE HIERRO-ARSENICO QUE TIENE UN RATIO MOLAR DE Fe/As DE 1/1; EL HIERRO TRIVALENTE ES PRODUCIDO EN FORMA SEPARADA POR DISOLUCION OXIDATIVA DE UNA FUENTE DE HIERRO USANDO BACTERIAS OXIDANTES
