Abstract

The present invention relates to a method for removing arsenic oxides from process exhaust gases, comprising the step of passing said exhaust gases through a phase layer consisting of an ionic liquid deposited on a carrier, characterized in that the ionic liquid contains one or more cations from the list consisting of substituted phosphonium, ammonium, imidazolium, pyrrolidinium and pyridinium, and one or more anions from the list consisting of chloride ion, bromide ion and carboxylate ion. Compared with an activated carbon layer, the same activated carbon layer impregnated with an ionic liquid according to the present invention can practically double the ability of the layer to adsorb arsenic, while at the same time significantly accelerating the course of the adsorption process.
