Simultaneous determination of Sunset yellow and Tartrazine in soft drinks using gold nanoparticles carbon paste 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.…”

“…Natural food dyes have been used more and more for consumer preference; however, synthetic food dyes are still widely used in food and feed industry because of their high stability to light, oxygen and pH, color uniformity, low microbiological contamination, relatively lower production costs, etc. [2].…”

“…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.…”

Oxidation and Complexation-Based Spectrophotometric Methods for Sensitive Determination of Tartrazine E102 in Some Commercial Food Samples

“…Therefore the determination of tartrazine in commercial food products is very important. Until now, different methods such as chromatography [6]- [12], electroanalytical methods [13]- [15] and spectrophotometry [16]- [24], have been reported for the determination of tartrazine. However, some of these methods are not suitable for routine monitoring as they are time consuming, complicated and have poor sensitivity and selectivity.…”

Application of a modified graphene nanosheet paste electrode for voltammetric determination of methyldopa in urine and pharmaceutical formulation

“…One of the most important properties of CMEs is their ability to catalyze the electrode process via the significant decrease of overpotential with respect to the unmodified electrode. With respect to the relatively selective interaction of the electron mediator with the target analyte in a coordinated fashion, these electrodes are capable of considerably enhancing the selectivity of electroanalytical methods (Beitollahi et al 2011a;Luo et al 2013;Taleat et al 2008;Huo et al 2013;Thomas et al 2013b;Raoof et al 2006b;Oliveira et al 2013;Beitollahi et al 2011b;Thomas et al 2013c;Mohammadi et al 2013;Sanghavi et al 2013;Beitollahi et al 2014;Li et al 2012;Ghoreishi et al 2012;Yildiz et al 2014).…”
