The invention relates to a process for the separation of a gaseous hydride or a mixture of gaseous hydrides from a gaseous medium containing at least one gas from the group consisting of H.sub.2, Ar, He, according to which the gaseous medium is passed on to a membrane module so that the concentration of the hydride or of the mixture of hydrides obtained at the outlet of the module is higher than their initial concentration in the gaseous medium.

The invention relates to a process for the electrolytic generation of arsine from an electrochemical cell provided with a cathode supplied with H.sup.+ and AsO.sub.2.sup.- ions where two concurrent reactions take place producing arsine and gaseous hydrogen respectively, and an anode where a reaction producing H.sup.+ ions takes place, the ratio of the H.sup.+ /As concentrations at the cathode being controlled and kept constant.
