Abstract

This study investigates the removal of naphthol-AS dye from aqueous solutions by SDS-modified adsorbents under various experimental conditions. Results imply that the adsorption process was highly pH-dependent and optimum pH for adsorption occurred at 6.0, having maximum removal efficiency of 91 %. Adsorption of Naphthol-AS on the adsorbent fitted better into the second order kinetic model and maximum adsorption capacity was found to be 4.803mg g−1. Equilibrium isotherms were best described by Langmuir isotherm with high-correlation coefficient value. The results of the study infer that SDS-modified iron filing is a promising adsorbent for the removal of dyes from wastewater.
