Silver particle-decorated carbon paste electrode based on ionic liquid for improved determination of nitriteMenart, Eva (Avtor) Jovanovski, Vasko (Avtor) Hočevar, Samo B. (Avtor) Silver particlesSquare-wave voltammetryNitriteIonic liquidCarbon paste electrodeA simple silver particle-modified carbon paste electrode is proposed for the determination of low concentration levels of nitrite ions. The electrode consists of a carbon powder decorated with silver sub-micrometre particles (AgPs) and a hydrophobic ionic liquid trihexyltetradecylphosphonium chloride as a binder. It has been shown that AgPs exhibit a strong electrocatalytic effect on the nitrite oxidation. For optimal electroanalytical performance the electrode was conditioned via silver oxidation/reduction cycle. The electrode revealed a linear square-wave voltammetric response in a wide examined concentration range of 0.05 to 1.0 mmol L− 1, limit of detection (LOD) of 3 μmol L− 1 and excellent repeatability with RSD of 0.3%.20152015-02-16 13:32:37Članek v reviji772UDK: 620.1/.2ISSN pri članku: 1388-2481DOI: 10.1016/j.elecom.2015.01.017COBISS_ID: 5639706OceCobissID: 2428442sl
