Abstract

Se remueve arsenico del agua y de otras alimentaciones acuosas por medio de (1) tratamiento de la alimentacion con un compuesto que contiene cerio en el estado de oxidacion +4, preferentemente dioxido de cerio, para oxidar arsenico en el estado de oxidacion +3 a arsenico en el estado de oxidacion +5 y (2) remocion del arsenico en el estado de oxidacion +5 de la fase acuosa, normalmente por contacto de la alimentacion tratada con aluminia u otro agente de precipitacion que contiene cationes en el estado de oxidacion +3.
