Abstract
Abstract Industrial wastewater inevitably contains pollutant and they can cause irreparable damage to the ecosystem when being released to the environment. Adsorption and photocatalytic degradation are two noteworthy treatment processes. In this research, the immobilization of both modified adsorbent and TiO2 in a thin film will be advantageous to the industries as the post-treatment recovery of photocatalyst and adsorbent can be avoided. Plackett–Burman design was employed to identify the significant factors in the removal of dyes whereas the optimum levels for maximum dye uptake were determined using Response Surface Methodology (RSM). Kinetic studies showed that all experiments fitted well in the first order kinetics model. The optimum condition for the remediation of dye from aqueous solution was found to be at pH 8, 5 mg/L initial concentration of dye and contact time of 300 min.
