“…Thanks to these qualities, the use of silver solid amalgam electrode (AgSAE) is possible in flow systems. Number of applications of amalgam electrodes such as HPLC-ED determination of catecholamines at gold amalgam electrode by multichannel amperometric detector [10], artemisinin, dihydroartemisinin, and artelinate at gold amalgam electrode [11] and FIA-ED determination of O(À II), Mn(II), Fe(II), I(À I), and HS(À I) in bioturbated sediments using gold amalgam microelectrode [12], cystine and S-sulfocystine using dual gold amalgam electrode [13] and 5-nitroquinoline and 6-nitroquinoline using meniscus modified AgSAE [14] have been described. The use of AgSAE for HPLC-ED has been only briefly mentioned [1,15].…”

The use of a silver solid amalgam working electrode for HPLC with electrochemical detection has been investigated. The thin-layer and wall-jet detectors based on this electrode were constructed and applied for the determination of a mixture of nitrophenols. The optimal separation and detection conditions for the determination of 2-nitrophenol, 4-nitrophenol, 2,4-dinitrophenol and 2-methoxy-5-nitrophenol in mixture were found using RP-HPLC at Nova-Pack C18 column and amperometric detection with the above mentioned detectors. It has been proved that the silver solid amalgam electrode is a suitable working electrode for HPLC-ED and provides sufficient sensitivity for determination of tested nitrophenols.

“…Normally, once the mercury is electroplated on a metallic surface, it forms amalgam with the metal and the surface properties are dramatically changed. Among them silver amalgam electrode (SAE) is the most popular and it is applied in the electrochemical determination of metal ions, organic, and biological compounds [5][6][7][8][9].…”

Anodic stripping voltammetry (ASV) is successfully applied in mM level detection of mercury ion in an electroplating bath which is currently used in preparing a cathodic electrolyzer. Glassy carbon electrode is used for the detection and the optimum condition obtained is 10 s deposition at -1.4 V vs. Ag/AgCl and stripping by scanning from -1.4 to +0.4 V vs Ag/ AgCl at 50 mV/s. By applying the method, the mercury ion concentration in the electroplating bath could be successfully monitored during the plating.

“…Electroanalytical methods are especially suitable for large scale environmental monitoring of electrochemically active organic pollutants because they are inexpensive, extremely sensitive and they present an independent alternative to so far prevalent spectrometric and separation techniques [1]. Development of sufficiently sensitive and selective voltammetric and amperometric methods for the determination of various environmentally important biologically active substances is the main task of our UNESCO Laboratory of Environmental Electrochemistry [2][3][4]. Quinolines and its nitroderivatives are among substances suspected of carcinogenity and mutagenity [5][6][7].…”

This work is focused on the application of a silver solid electrode (AgE) for the development of modern voltammetric methods for the determination of submicromolar concentrations of biologically active compounds present in the environment. 8‐Nitroquinoline (8‐NQ), a well‐known chemical carcinogen, was chosen as a model substance. Differential pulse voltammetry (DPV) was used to study electrochemical behavior of 8‐NQ in different aqueous matrices. The following optimal conditions for determination of 8‐NQ in the concentration ranges from 2 to 100 µmol L−1 were used: BrittonRobinson (BR) buffer of pH 3.0, the regeneration potentials cycles (Ein=−1000 mV, Efin=−100 mV) and constant cleaning potential −2000 mV. Practical applicability of AgE for the determination of micromolar concentrations of 8‐NQ was verified on model samples of drinking and river water.
