Zusammenfassung:	FIELD: purification of gases. ^ SUBSTANCE: method comprises mixing hydrogen sulfide containing gas with a water oxidizing absorbing solution based on the bischofite having chromate of alkaline earth metal or its mixture with chromate of alkaline metal. The mixing is carried out at a Ph value of at least 7 in the temperature interval from the freezing point of the solution to +60°C. The exhaust absorbing solution is regenerated by air at a temperature above +25°C or active oxygen in the temperature interval from the freezing temperature of the solution to +25°C. ^ EFFECT: expanded functional capabilities. ^ 1 tbl
