Removal of sunset YellowAzo dye using activated carbon entrapped in alginate from aqueous solutions

Abstract

The aim of this research is for decreasing contaminants using alginate beads with activated carbon entrapped (AG-AC) by adsorption. Different sunset yellow FCF concentrations were prepared in the laboratory. The effect of the different parameters was studied (pH, contact time, adsorbent dose, stirring rate, and concentrations) on the removal processes. The results were analyzed according to the Langmuir, Temkin, Freundlich, and Dubinin-Radushkevich adsorption isotherms. The removal efficiency is more appropriate by the Langmuir isotherm. Sunset yellow FCF (10 ppm) percent removal efficiency is (86%) at pH 3 and 10 g\L of the adsorbent dose for 30 min with a fixed stirring rate (100 rpm). The effect of different operating parameters was investigated using Linear regression analysis which occupies more than 97 % of the total of the variables affecting the removal process. Finally, I recommend using this technology for Removal of Sunset Yellow FCF.

Study the Interaction Adsorptive Behavior of Sunset Yellow Dye and Loratadine Drug: Kinetics and Thermodynamics Study

“…Many production processes, like those in the food, pharmaceuticals, cosmetic, textile, and leather trades, utilize sunset yellow as a colorants material. When these azo dyes are used frequently, it could really lead to many health risks such allergic reactions, chromosomal abnormalities, and hyperactivity in children [8]. Contrarily, drugs administered as pharmaceuticals are often aromatic hydrocarbons compounds that have an effect on the whole organism.…”
