Abstract
A new simple ion-seleotive electrode poly (vinyl chloiidej membrane sensor foi Mg (II) ions
based on magnesium Salicylate as a new ionophore has been prepared and studied 1 he electrode
exhibits a good potentiomotric response for Mg (It) ion over a wide concentration range 1 Ox 10' to
1 0x10 N with a slope value ol electrode-1 was 23 mv/decade and 2(1 mv/decade loi niectiDde-ll
The elecliocle can be used over ? months with good lepioducibilily 1 he senso' was" ised as an
indicaloi electiode in n polontiometiic titration ol Mg (II) ions against (-DTA 1 he sensi t was used
