“…International Agency for Research on Cancer (IARC) has classified these Sudan dyes as category 3 carcinogen (Ávila et al 2011). Consequently, the addition of Sudan dyes to foodstuff is forbidden in any national and international food regulation act (Qiao et al 2011). Unfortunately, the illegal use of the dyes has still been found in varieties of foodstuffs due to their fresh color, colorfastness, wide availability, and low cost (Schummer et al 2013).…”

Solidification of ionic liquid (SIL) has been applied in microwave-assisted liquid-liquid microextraction method for analyzing Sudan dyes in juice samples. 1-Ethy-3-methylimidazolium hexafluorophosphate ([C 2 MIM][PF 6 ]) was selected as the extraction solvent due to its relatively high melting point. With the aid of microwave irradiation, the dyes could be easily extracted into ionic liquid phase without dispersive solvent. The solid microdroplet could be easily separated from liquid. Compared with traditional dispersive liquidliquid microextraction, this method will greatly simplify the collection procedure and shorten the operation time. Several experimental parameters, including the amount of ionic liquid, microwave power and irradiation time, pH of sample solution, and ionic strength, were systematically investigated and optimized. The limits of detection for Sudan I, II, III, and IV were 1.08, 1.30, 1.14, and 1.19 μg/L, respectively. The recoveries of the analytes ranged from 83.42 to 115.56 % and relative standard deviations were lower than 11.53 %, when the present method was applied to the analysis of real samples.

“…To date, there have been many methods for the determination of Sudan I, including liquid chromatography (Chailapakul et al, 2008;Qi, Zeng, Wen, Liang, & Zhang, 2011;Qiao, Geng, He, Wu, & Pan, 2011;Xin et al, 2011;Yan et al, 2012;Zhang et al, 2012), capillary electrophoresis (Mejia, Ding, Mora, & Garcia, 2007), immunoassay (Chang et al, 2011;Oplatowska, Stevenson, Schulz, Hartig, & Elliott, 2011;Wang, Yang, Ga, & Deng, 2011), high-resolution 1 H nuclear magnetic resonance spectrometry (Anibal, Ruisánchez, & Callao, 2011), partial filling micellar electrokinetic chromatography (Fukuji, Castro-Puyana, Tavares, & Cifuentes, 2011), and plasmon resonance light scattering (Wu, Li, Huang, & Zhang, 2006). The determination of Sudan I using these techniques shows high sensitivity, but they require expensive instruments, pre-treatment steps, skilled operators, and large quantity of organic solvents.…”

Dyes are used in different industries as textile, paper, food processing, cosmetic, leather tanning, rubber, printing and so on. These chemical substances have negative effect on the quality of the water and food, causing human diseases and environmental problems. In view of these aspects, colorant have attracted the interest of the scientists in developing efficient routes for their detection and/or removal from the polluted sites. Although traditional technologies used for removal of dyes are efficient, there is the necessity of developing innovative systems both more cheaply and of easy performance. In this scenario, the integration of the membrane science with the molecular imprinting technology is an alternative way that present many advantages such us the removal or detection of a specific dye or a class of dyes and cost reduction processes. In fact, exploiting the benefits of these two technologies it is possible to develop molecularly imprinted membranes able to recognize a dye of interest in specific mode. This potential is promising for combatting the illegal use of dyes in food, drinks and aquaculture as well as for their removal. The main positive aspects of the imprinted membranes are their chemical stability, reusability, as well as the resistance to the pH and temperature. In addition, their preparation requires short operation time and it is not expensive. All these properties have an encouraging impact in dealing with the problem of dyes contamination. This short review offers a description of the concept of molecular imprinting, starting from the approach of the synthesis of imprinted polymers until the description of the preparation of imprinted membranes. The application of imprinted polymers and membranes for the detection and/or removal of dyes from polluted sites will be also discussed.
