Trialkyl arsines are removed from fluids, in particular gases, by contacting with a solid sorbent material containing at least one manganese oxide (preferably MnO.sub.2) and at least one Group IB metal oxide (preferably CuO). In a preferred feature, the used solid sorbent material is regenerated by oxidizing treatment, washing with an aqueous liquid, and drying.
