## Abstract A new modified carbon paste electrode (CPE) based on a recently synthesized ligand of Ethyl‐2‐(benzoylamino)‐3‐(2‐hydroxy‐4‐methoxyphenyl)‐2‐propenoate (EBHMP) as a suitable carrier for Hg^2+^ ion was described. The electrode exhibit a super Nernstian slope of 48.5±1.0 mV per decade for
The determination and speciation of copper at a carbon paste electrode modified with Dowex 5OW-8X cation-exchange resin was investigated in model and real samples. With this procedure free metal ions and labile complexes can be measured which dissociate during the time scale of the chemical accumula
