Statistical Optimization for the Adsorption of Acid Fuchsin onto the Surface of Carbon Alumina Composite Pellet: An Application of Response Surface Methodology
Monal Dutta and Jayanta Kumar Basu

Abstract: Industrial effluents mainly enriched with different colored substances cause significant environmental problem. Various efforts have been made so far for the treatment of textile industry effluents but very little attention has been given for the removal of dyes from medicine industry waste water. Acid fuchsin is one of such dyes which are mainly present in the medicine industry waste water. In the present investigation, carbon-alumina composite pellet was developed for the removal of acid fuchsin dye from its aqueous solution. The removal of acid fuchsin was carried through batch adsorption and the effects of different parameters on the adsorption of acid fuchsin were studied through response surface methodology. The composite adsorbent was found to have an adsorption capacity of 181.82 mg g-1 for acid fuchsin. The adsorption process was optimized by using response surface methodology and the effects of various process parameters such as, temperature, solution pH, salt concentration and initial dye concentration on percent dye removal were determined by a four factor Box-Behnken design. The maximum dye removal percentage was obtained for an initial dye concentration of 10 mg L-1 and a solution pH of 7.5 whereas, the temperature is fixed at 35°C. Nevertheless, the maximum removal was found at zero salt concentration. Therefore, it can be concluded that the prepared adsorbent successfully remove acid fuchsin from its aqueous solution. Since the adsorbent is used in the pelletized form, it can be further used in a fixed bed column study.
