Abstract: A process for the removal of hydrogen sulfide from a gas which comprises contacting the gas with a solution comprising ferric ions (Fe.sup.3+) and ferrous ions (Fe.sup.2+). The solution further comprises ethylenediamine tetraacetic acid (EDTA) or a salt thereof and triethanolamine (TEA) or a salt thereof. The solution has a pH in the range of from 7 to 9 and a mole ratio of ferric ion to total iron ions in the range of from 0.60 to 0.90 as measured just after the hydrogen sulfide contacts the solution. The process is characterized by high removal of hydrogen sulfide, prevention of side reactions, and the inhibition of the formation of intermediate colloidal sulfur.
