摘要：

A simple galvanic cell without any external voltage for the trace determination of hydrogen sulphide is described. The signal corresponds to the concentration of the dissolved molecular H2S. For the calculation of total sulphide, the pH has to be taken into consideration. The sensor was tested in the range of concentration from 3 . 10(-6) mol/l H2S to 9 . 10(-5) mol/l H2S for pH < 5. For pH 7.8 it covers a range from 1 . 10(-6) mol/l H2S to 1 . 10(-5) mol/l H2S. The sensitivity of the sensor substantially depends on the pH of the aqueous medium.
