Carbon paste electrodes have been modified with some lipidsfor the sensitive and selective detection of the antidepressant (Desipramine). Voltammetric experimental conditions were optimized taking into account the importance of quantifying desipramine in the complex media and in the pharmaceutical formulations. The sensor(Lauric acid modified carbon paste electrode) responds to desipramine givi...

In this paper we study the influence of substituting one CO ligand in [Fe2(CO)6{μ-(SCH2)2(Ph)P=O}] (1) by better σ-donor L ligands affording [Fe2(CO)5(L){μ-(SCH2)2(Ph)P=O}] {L = PPh3 (2) and P(OEt)3 (3)} in relation to the steric interactions and the voltammetric behavior. Cyclic voltammetric investigations under N2 and CO showed remarkable differences in the electrochemical behaviour of comple...

A voltammetric sensor based on a composite of polyarylene phthalide and graphitized carbon black Carboblack C modified with chelate complexes L-argenato-L-alaninate copper (II) has been developed for the recognition selective determination tryptophan enantiomers. The conditions modifying are optimized, effective surface area (A = 4.38 ± 0.06 mm2) resistance (Ret 1.29 0.08 kΩ) calculated. optima...

Stripping voltammetry as technique has proved to be very useful in the analysis of heavy and other metal ions due to its excellent detection limits and its sensitivity in the presence of different metal species or interfering ions. Recent assessments of aquatic samples have shown increased levels of platinum group metals (PGMs) in aquatic ecosystems, caused by automobile exhaust emissions and m...

A sensitive adsorptive stripping procedure (square wave adsorptive stripping voltammetry), was developed to study the adsorption property of Eosin-Y dye on a working electrode (HMDE) and its determination in selected samples. In addition, differential pulse polarographic and cyclic voltammetric methods were used to evaluate the electrochemical preliminary studies of Eosin-Y dye. By means of usi...

This review examines basic principles and applications of voltammetric electronic tongues. It is introduced by a description of the concept of electronic tongues or taste sensors followed by a general overview of electrochemical measurement principles that have been used for electronic tongues. A special emphasis is given on measurement principles for voltammetric electronic tongues, also inclu...
