The CO2 content in H2S is around 3%. Laboratory methods are sufficient; large-scale industrial methods are not needed.

Pass a supersaturated calcium sulfide solution through

:shutup:. . . Try using a saturated solution of sulfides; I checked specifically about calcium sulfide, and it’s practically insoluble. What kind of experiment are you trying to conduct? . .

Try using a saturated solution of sodium sulfide or a saturated solution of calcium hydroxide/lime milk; it should work

Don’t both Na2S + H2S = 2NaHS and Ca(OH)2 + H2S = CaS + 2H2O react with H2S?
