A silica gel-modified carbon paste electrode (Si-CPE) was fabricated and used for selective and sensitive determination of insulin. The experimental results suggested that insulin effectively accumulated on surface of the modified electrode resulting in a marked enhancement of its oxidation current

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
