Abstract

A concentration measuring apparatus for hydrogen sulfide includes an absorbing liquid that can absorb gaseous hydrogen sulfide as sulfide ion; a hollow fiber membrance contactor that contacts a gas flow with a flow of the absorbing liquid absorbs gaseous hydrogen sulfide in the gas flow as sulfide ion ; a pump for a first channel that feeds the absorbing liquid to the hollow fiber membrane contactor; an oxidizer that exothermically reacts with sulfide ion , a pump for a second channel that feeds the oxidizer to the absorbing liquid , a first thermometer that measures a temperature of the absorbing liquid has absorbed exothermically reacts with the oxidizer, and a second thermometer that measures the temperature of the absorbing liquid after the sulfide ion that the absorbing liquid has absorbed exothermically reacts with the oxidizer
