Carbon-paste electrodes modified with crown-ethers were constructed by mixing the crown-ethers into a graphite powder/Nujol oil matrix. The electrodes so formed were able to bind mercuric ions chemically, and gave greater voltammetric response to mercury than that of ordinary carbon-paste electrodes. The response was characterized with respect to paste(More)
The amperometric performance of two types of chemically modified carbon electrodes developed for the determination of oxides of nitrogen in continuous-flow systems is presented. The modification consists in immobilization of reversible Fe(II)/Fe(III) centers. The first type of electrode is a simple modification made by direct mixing of carbon paste with(More)
