Abstract
Methods of purifying HSe by removing HS and/or HO are disclosed. The amount of HS in the HSe-containing gas is reduced below 10 ppmv by passing the HSe-containing gas through an AW-500 molecular sieve. HS and HO are removed by passing HSe through a 4 A molecular sieve and subsequently passing HSe through an AW-500 molecular sieve.
