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.
