Phenol and its derivatives are known to be toxic causing adverse impact on human health
and environment. Adsorption utilising waste materials is a cost effective method for
abatement of such pollutants. The present study thus aims to remove the phenol from
aqueous solutions using chitosan/calcined eggshell adsorbent. Taguchi L 27 Orthogonal
array design methodology was used for the optimization of preparation variables. The
statistical results obtained using ANOVA and S/N ratios showed that adsorption of phenol …
