FIELD: adsorbents.
SUBSTANCE: invention relates to the field of manufacturing and application of adsorbents. An adsorbent composition, which is a bismuth-based material in an amount of 2% to 50% by weight, containing bismuth in the oxidation state +3, contacts the stream to adsorb an arsenic-containing material such as arsine.
EFFECT: invention ensures effective arsine adsorption.
