Abstract

In this study, the application of adsorption process in the treatment of wastewater containing styrene has been evaluated and for optimizing process conditions, the surface response method (RSM) has been used. In this method, the experiments were performed on the basis of the central combination design, based on the change in contact time, pH, initial concentration of styrene and the amount of adsorbent as an effective factor in removal of styrene. In the first section, the PANIL/Fe3O4 nanoparticle absorbent was used to detect adsorbent analyzes of VSM, EDX, FT-IR and SEM. Analysis of variance shows that the obtained relationship to remove styrene has the ability to match the experimental data to 0.949. The best conditions for removal of styrene, contact time of 5 minutes, pH 6, initial concentration of styrene 40 ppm, and adsorbent content of 0.08 g were obtained. First-order and quadratic kinetic models were investigated, which showed that the pseudo-second-order model (R2=0.99) showed the highest correlation with experimental data. The absorption parameters of styrene were evaluated using three models of Tamkin, Langmuir and Freundlich absorption symmetry. Considering simultaneously the two correlation coefficients, the Tamkin model (R2=0.99) showed the best fit to the absorption data.
