Simultaneous voltammetric determination of synthetic colorants in food using a cathodically pretreated boron-doped diamond electrode

Formation of graphene nanoplatelet-like structures on carbon–ceramic electrode surface: application for simultaneous determination of sunset yellow and tartrazine in some food samples

“…Comparison of the response characteristics for determination of SY and Tz at various modified electrodes was presented in Table 1. In comparison with other modified electrodes reported previously [2,10,11,[30][31][32][33], the proposed modified electrode possesses unique properties. Firstly, it possessses all the advantages of CCE and also benefitted from the advantages of ionic liquid and graphene nanoplatelet-like structures formed on the CCE surface because of ionic liquid deposition.…”

Differential pulse voltammetric determination of albendazole in pharmaceutical tablets using a cathodically pretreated boron-doped diamond electrode

“…whether they are predominantly hydrogen or oxygen terminated [21]; the predominance of a termination type can be attained by proper electrochemical pretreatments. This effect of surface termination was observed, for instance, in the determination of additives in food products [22][23][24] and of drugs in pharmaceutical formulations [25][26][27][28], when cathodically pretreated (predominantly hydrogen-terminated) BDD electrodes presented better performances.…”

“…Consequently, all subsequent experiments were carried out using a cathodically pretreated BDD. Previously, better results were also obtained in the analysis of several analytes when a predominantly hydrogen-terminated BDD electrode was used [22,24,25,28,35].…”

Determination of Brilliant Blue FCF by a Novel Solid-state ECL Quenching Sensor of Ru(bpy)32+-poly(sulfosalicylic acid)/GCE

“…3 The reported methods for BB FCF determination include spectrophotometry, 4,5 capillary electrophoresis, 6 highperformance liquid chromatography (HPLC) 7,8 and voltammetry. 9,10 Among these methods, electrochemical techniques have many advantages including low cost, fast response, high sensitivity, and good reproducibility.…”
