“…The adsorption of tartrazine onto the nanocomposite can be ascribed to the interaction between functional groups of nanocomposite and analyte which depends on pH alterations. The interaction between tartrazine and MIP nanocomposite is caused by hydrogen bonding and electrostatic interaction between undissociated amide groups on nanocomposite surface and sulfonated groups of the dye [52]. The results showed that with increasing the concentration, photodegradation decreases (Fig.…”

In this research, a nanocomposite of molecularly imprinted polymer (MIP)-nanophotocatalyst for enhanced photodegradation of tartrazine with high efficiency and nanocomposite of non-imprinted polymer (NIP)-nanophotocatalyst were synthesized by precipitation polymerization and it was carried out in an aqueous medium to employ a green method. Acrylamide as functional monomer, N,N´-methylene-bis-acrylamide as cross-linking agent, tartrazine as a template, and TiO 2 as a nanophotocatalyst were used. The synthesized nanocomposites (MIP-TiO 2 and NIP-TiO 2 ) were characterized by using thermal gravimetric analysis, scanning electron microscopy, transmission electron microscopy, and Fourier transform infrared spectroscopy. The MIP nanocomposite as an effective sorbent was used to extract and photodegrade tartrazine from water media. The effects of pH, time, and concentration of tartrazine solution and kinetics of photodegradation of tartrazine were investigated. The best pH and the optimum time for tartrazine photodegradation in a 10 ml solution containing tartrazine (3 × 10 −5 M) and nanocomposite (1 mg) were obtained to be 2 and 5 h, respectively. The results showed that the MIP nanocomposite has improved the photodegradation of tartrazine by 100% compared to NIP nanocomposite and pure nanophotocatalyst which yielded at 63 and 56%, respectively, under the same condition.

In the present study, for the first time electromembrane extraction followed by high-performance liquid chromatography coupled with ultraviolet detection was developed and validated for the determination of tartrazine in some food samples. The parameters influencing electromembrane extraction were evaluated and optimized. The membrane consists of 1-octanol immobilized in the pores of a hollow fiber. As a driving force, a 30 V electrical field was applied to make the analyte migrate from sample solution with pH 3, through the supported liquid membrane into an acceptor solution with pH 10. Best preconcentration (enrichment factor >21) was obtained in extraction duration of 15 min. Effects of some solid nano-sorbents like carbon nanotubes and molecularly imprinted polymers on membrane performance and electromembrane extraction efficiency were evaluated. The method provided the linearity in the range 25-1000 ng/mL for tartrazine (R(2) > 0.9996) with repeatability range (RSD) between 3.8 and 8.5% (n = 3). The limits of detection and quantitation were 7.5 and 25 ng/mL, respectively. Finally, the method was applied to the determination and quantification of tartrazine from some food samples with relative recoveries in the range between 90 and 98%.

Since natural pigments are lost during the processing of beverages such as pomegranate juice, carmoisine, as an adulterant, is often added into the pure juice to improve color characteristics. In this study, molecularly imprinted polymers, as an adsorbent of carmoisine, were synthesized using acrylamide, methacrylic acid, and 4-vinylpyridine as functional monomers and then they were evaluated in terms of the separation and detection of carmoisine. Experiments on the batch adsorption of carmoisine 10 ppm stock solution revealed a better binding capacity for the 4-vinylpyridine-based polymer in comparison to methacrylic acid and acrylamide polymers. The complexation of carmoisine with the 4-vinylpyridine-based polymer was confirmed by Fourier transform infrared spectroscopy. The synthesized polymer exerted a high thermal degradation point and average diameter of polymer particles were obtained to be 0.2 μm by dynamic light scattering analysis. This work showed that detection of pomegranate juice adulteration with carmoisine is not necessarily difficult, time consuming or expensive with selective separation techniques such as molecularly imprinted polymers.
