Abstract:In this paper describes the resulte of a potentiometric investigaion of the N -methly - N ' - antipyrlthiourea (M A ppU ) and N, N' - diantipyrlthiourea (DAm ), with asulphide ion-Selective electrode as the indicator and with a double-saturated Calomelreference electrode in O.2mol' dm-' sodium hydroxide. The main factors affecting theelectrode reaction equilibrium and interfering ion are discussed. lt also investigaed themethod to get rid of interfering ion.
