The potential feasibility of layered double hydroxides for removal of sunset yellow dye FCF from aqueous solution was investigated. The effects of various experimental parameters such as contact time, solution pH, dye concentrations and adsorbent dosage were investigated. The extent of sunset yellow FCF dye removal increased with the increased in contact time and amount of layered double hydroxides used however the percentage removal was decreased with the increased in pH and dye concentrations. Adsorption data was better fitted to the Langmuir isotherm. The results in this study indicated that layered double hydroxide was an attractive adsorbent for removing sunset yellow FCF dye from aqueous solution.
