Voltammetric characterization of Hg2+ ion behaviour in acid media on different electrodes

Voltammetric Behaviour of Metronidazole at Mercury Electrodes

Metronidazol é o fármaco mais importante do grupo de 5-nitroimidazoles, possuindo toxicidade contra microrganismos anaeróbicos, sendo a molécula de DNA o principal alvo de sua ação biológica. O mecanismo de ação do metronidazol depende do processo de redução do grupo nitro e, em meio ácido, a redução é pH-dependente envolvendo quatro elétrons na completa redução ao derivado hidroxilamínico. Em ...

The Effect of Different Electrodes on Humic Acid Removal by Electrocoagulation

The present study is about the reduction of humic acids (HA) by electrocoagulation (EC) method. Undesirable color, odor, taste, reacting with chlorine to produce toxic materials in water, and making a complex with heavy metal ions are some unfavorable environmental consequences of HA. Platinum and graphite as anode electrodes and platinum, titanium, and aluminum as cathode electrodes were used ...

Voltammetric determination of trace mercury in chloride media at glassy carbon electrodes modified with polycationic ionomers

The perfluorinated polycationic polymer Tosflex @ is used for preparing polymer modified electrodes able to preconcentrate and detect the anionic complex HgCl$-, which is the prevailing inorganic Hg(II) species in sea water and other chloride media. The study of the ion-exchange voltammetric behaviour of the tetrachloromercurate(I1) complex at Tosflex-modified electrodes indicates the efficient...
