“…Depending on their structure, they can be divided into several categories such as azo, vat, indigo, nitro dyes, etc., the first, azo, representing more than 60% of the market [ 1 ]. Since it is common for synthetic dyes to be used in the production of goods as textiles [ 2 , 3 ], cosmetics [ 4 , 5 , 6 ], food [ 7 , 8 , 9 ], plastics [ 10 ], drugs [ 11 , 12 ], etc., they are obtained in large quantities. Part of them end up in water, either through the products in which they are found or as part of the discharged effluents thus becoming a source of contamination.…”

The treatment of contaminated water is currently a major concern worldwide. This work was directed towards the preparation of a composite hydrogel by entrapping cherry stones powder on chitosan, which is known as one of the most abundant natural polymers. The synthesized material was characterized by scanning electron microscopy, by Fourier transform infrared spectroscopy, and by the point of zero charge determination. Its ability to remove two azo dyes models (Acid Red 66 and Reactive Black 5) existing in single form and in binary mixture was evaluated. Response Surface Methodology–Central Composite Design was used to optimize three parameters affecting the process while targeting the lowest final contaminant concentrations. The best results were obtained at pH 2, an adsorbent dose of 100 g/L, and a temperature of 30 °C, when more than 90% of the pollutants from the single component systems and more than 70% of those of the binary mixtures were removed from their aqueous solutions. The adsorption process was in accordance with Elovich and pseudo-second-order kinetic models, and closely followed the Freundlich and Temkin equilibrium isotherms. The obtained results led to the conclusion that the prepared hydrogel composite possesses the ability to successfully retain the target molecules and that it can be considered as a viable adsorbent material.

“…Another challenge is the potential interference from other compounds present in the food matrix, which can affect the accuracy and reliability of the measurements. 9,10 Therefore, it is recommended to use analytical methods to measure these colors.…”

One of the most important edible colours is used in various industries is Sunset Yellow, which is essential to measure according to its consumption. Therefore, a new electrochemical sensor is prepared to measure the food color additives in this work. In this study, CuNiFe2O4 nanospheres to prepare a potent modifier for carbon paste electrode (CPE). Due to environmental toxicity of food color additives, its sensitive, fast and, low-cost determination in workplace environments is of great interest. So, the modified CPE was applied as a sensitivity analysis approach for Sunset Yellow in present Brilliant Blue and Tartarzin in plasma samples. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were used as techniques to optimize the analysis and measurement of Sunset Yellow. The calibration curve showed a linear range from 0.5 to 150 μM with a detection limit of 0.15 μM for Sunset Yellow. Simultaneous measurement of three colors, Sunset Yellow, Brilliant Blue and Tartrazine, is done on CPE/CuNiFe2O4 nanospheres surface and in simultaneous measurement received detection limits are 1.60 μM. The prepared sensor shows an outstanding ability to measure sunset in Sunich syrup and edible jelly as real samples.
