Abstract

To restrict contamination to the environment, basic wastewater treatment plants eliminate organic and suspended solids. The evolution of treatment techniques to remove dissolved materials and harmful compounds has been forced by advances in needs and technology. Currently, advances in scientific understanding and moral awareness have resulted in a decrease in discharges through pollution control and recycling, with the lofty goal of zero pollution discharge. The major purpose of this research was to see how well Polyaniline adsorbents that have been functionalized with Bentonite performed. To synthesize polyaniline/bentonite nano composite (PAN/B), the process relies on induced bentonite during aniline polymerization.

SEM, BET, FTIR, and EDAX investigations were employed to recognize the adsorbent, which was then exploited as a possible naphthalene adsorbent for effluent treatment. pH, adsorbent dose, contact time, and starting pollutant concentration were investigated as experimental factors impacting naphthalene sorption onto the PAN/B nanocomposite.

The pseudo-second-order model best expressed the naphthalene adsorption when the kinetic data were assessed. The equilibrium data was fit to isotherm models, with the Langmuir model delivering the greatest fit to the naphthalene removal experimental data.
