Abstract
A total dissolved sulfide meter was designed and tested over the concentration range 10−5 to 10−1 mol/L. The Instrument applies a sulfide ion activity electrode and a pH glass electrode, whose potentials are measured against a double junction reference electrode. The potentials are processed by an electronic analog circuit to obtain an output voltage that is proportional to total dissolved sulfide. The proposed instrument—adjustment procedure eliminates mutual dependence of the adjusted controls. The total dissolved sulfide readings of the instrument were found to be pH independent over the pH range pH 7.5 to pH 11.5.
