Oxime-2-(1-cyclohexenyl) Cyclohexanone: Synthesis and Application as a New Ion Carrier for Preparation of Cobalt Selective Potentiometric Electrode

In this paper, a new cobalt selective liquid membrane electrode has been constructed by using a new synthesized oxime-2-(1-cyclohexenyl) cyclohexanone in a poly (vinyl chloride) matrix. the electrode was shown a good nernstian response for co^2+ (32.1±0.5) over a concentration range of (3.0×10^-2 to 7.0×10^-7 mol l^-1). the electrode detection limit was 6.0×10-7 mol l^-1. the response time of electrode was fast (∼10 s) and useful working ph range was 3.5-8.5. it can be used over a period of 15 weeks without any divergence in potential. the proposed electrode revealed good selectivity for co^2+ over a wide variety of other metal ions. the co^2+ ion sensor has been practically utilized as an indicator electrode in potentiometric titration of co^2+ with edta. also, direct determination of co^2+ in water and battery wastewater samples was done to confirmation of analytical ability of electrode.
