“…Various methods such as spectrophotometry [4], high-performance liquid chromatography (HPLC) [1,5], and spectrophotometry with chemometric analysis [6,7] have been reported for determination of SY and Tz. Moreover, voltammetric methods [2,[8][9][10][11] have been used for their determination based on electroactivity of SY and Tz.…”

Carbon-ceramic electrode modified with 1-allyl-3-methyl imidazolium tetraflouroborate ionic liquid was constructed. Scanning electron microscopy, X-ray diffraction analysis), energy dispersive X-ray analysis proved that the deposition of ionic liquid on the surface of carbon-ceramic electrode caused formation of graphene nanoplatelet-like structures on its surface. This electrode was used for simultaneous electrochemical determination of sunset yellow (SY) and tartrazine (Tz). Operational parameters such as pH of solution and ionic liquid volume which affected the analytical performance of modified electrode were optimized. The present electrode exhibited linear response to SY and Tz in concentration range of 1×10 −7 -1.5×10 −5 M and 1×10 −7 -2×10 −5 M with a detection limit of 7.3×10 − 8 M and 8.1×10 −8 M, respectively. The high repeatability, reproducibility, long-term life time, and low response time (<3 s) are advantages of modified electrode. The modified electrode was successfully applied for simultaneous determination of SY and Tz in different food samples, and the results were in good agreement with those obtained from HPLC method.

“…Distribution of the types of coloring additives used in food in the 1992 world market [23]. [37], a method was developed for the determination of the synthetic food colorants Tartrazine, Allura Red, and Sunset Yellow by DPP. Using as a response, for the three analytes, the signal intensity related to the reduction of the azo to hydrazo group on the surface of a DME, linear relationships were obtained between 0.050 and 7.5, 0.050 and 7.5, and 0.050 and 10 µmol L…”

Applications of the Voltammetry

Since 1856 when W. H. Perkin synthesized the first synthetic dye (Mauveine), a wide variety of colors and shades are produced and used in several commercial products. The occurrence in water and wastewater has gained controversy regarding their toxicity and mutagenicity and it has been regulation by several regulatory agencies. Thus, analytical methods able to determine these colorings in several matrices with high sensitive and robust enough are relevant. Among several analytical methods, the use of electroanalytical methods, especially the voltammetric techniques, are of great interest due to the high selectivity, sensitivity, use of low quantity of sample, little or without sample treatment, and low waste generation, which contributes to reduced environmental impact. Over the past decades, the technical based on current-potential curves by using of static electrodes have gained considerable progress, as minimizing the effect of capacitive current and the possibility of pre-concentration of the analyte at the electrode surface, which has reflected in lower detection levels. The present work gives an overview about the analytical methods available in literature focusing on electroanalysis of dyes by using voltammetric techniques. The advances of the electroanalytical techniques and the use of different modifiers to increase sensitivity and selectivity are reviewed.

“…To avoid time-consuming clean-up procedures, attempts to resolve complex spectra by using instrumental approaches or various chemometric methods have been made. Derivative techniques (Altionz and Toptan 2002;Altinoz and Toptan 2003;Kiroglu and Ozdemir 2000) and multivariate statistical analysis (Koyuncu et al 2003;Oveisi et al 2003;Dinc et al 2002;Lopez-de-Alba et al 2002;Pravdova et al 2002;Berzas Nevado et al 1999) have been successfully applied to the multi-component analysis of mixtures by UV/Vis molecular absorption spectrophotometry. All these approaches are useful for the reduction of band-overlapping errors in quantitative analysis, but they are often used for more complex mixtures.…”

A new, simple, sensitive, and inexpensive method for simultaneous determination of binary mixtures of food colorants, carmoisine and ponceau 4R, which are species with highly overlapped spectra, by using H-point standard addition method (HPSAM) is proposed. Absorbances at the two pair of wavelengths, 460 and 549 nm or 490 and 541 nm, were monitored while adding standard solutions of carmoisine or ponceau 4R, respectively. The accuracy and reproducibility of the determination method for various known amounts of carmoisine and ponceau 4R in their binary mixtures were evaluated. This method was satisfactorily applied for the determination of carmoisine and ponceau 4R in synthetic binary mixtures and several commercial products. The total relative standard error for applying the HPSAM to five synthetic samples was 3.26% or 4.96% with carmoisine or ponceau 4R addition, respectively.
