Abstract

PURPOSE: To make it possible to measure hydrogen sulfide residing the air and water at a high response speed, with high reproductivity and stably for a long period, by arranging a gas permeable diaphragm, detection electrode, opposite electrode, and inside liquid of specific pH in the support tube of a sensor which measures continuously hydrogen sulfide.
CONSTITUTION: Support tube 31 is provided with gas permeable diaphragm 37 and inside of the support tube, detection electrode 33 for silver sulfide, etc., opposite electrode 35 such as a chlorine ion electrode, and inside liquid 32 of more than pH8.1, preferably between 8.1 and 13.0 are arranged to obtain a hydrogen-sulfide measuring sensor. As the inside liquid, a solution of tris(hydroxymethyl)aminomethane and that of tris(hydroxymethyl)-aminomethane and alkali mixed are used.
