Comparison of Meniscus (m-AgSAE), Film (MF-AgSAE) and Polished (p-AgSAE) Amalgam Electrodes
Fadrná, Renata
Silver solid amalgam electrode (AgSAE) is a suitable alternative to hanging mercury drop electrode (HMDE). There exist three types of AgSAE varying in different surfaces: meniscus modified (m-AgSAE), film (MF-AgSAE) and polished (p-AgSAE) electrode, which does not contain any liquid mercury. This work presents the comparison of the process and time heftiness of the electrodes pre-treatment and their electrochemical properties.
Polished Silver Solid Amalgam Electrode
Fadrná, Renata
The polished silver solid amalgam electrode (p-AgSAE) seems to be a suitable alternative to hanging mercury drop electrode (HMDE). The structure of electrode material and working electrode surface were analyzed by RTG diffraction, atomic forces microscopy (AFM) and scanning electron microscopy (SEM). It was found that silver amalgam has crystalline structure (without the presence of different phases), any liquid mercury is not presented on the electrode surface and also mercury is not evaporated from the amalgam. p-AgSAE was applied for the determination of inorganic cations (Cu2+, Pb2+, Cd2+, Zn2+) and anions (NO3-, SCN-), amino acids (cysteine, cystin), nitro compounds (2,4´-dinitritoluene, 1,3´-dinitrobenzene, 2-nitronaftalene), aldehydes (benzaldehyde), vitamin C and purine bases of DNA (adenine, guanine) up to now.
