Abstract
In that work , we Adopt Preparation anew Carbon Paste electrode for Cerium ions based on complex (1,3-di phenyl-5- paranitrophenylFormazan) With Cerium Ions As electroactive material , This electrode revealed good Selectivity For Cerium Ions over wide variety of other metal ions. The electrode exhibited a Nernstain slope of (15±1) mv per decade of Cerium Ions over concentration range of (1ˣ 10-1 - 1ˣ 10-7) M in The PH range (3 -6.8). The response time was about (20) s and the detection limit was( 7ˣ 10 -7) M. The Electrode can be used for at least one month without a considerable divergence in potential .the proposed electrode was used for determination of Cerium in a standard solations and was successfully applied as an indicator electrode for potentiometric titration of Cerium Ions with EDTA.
