Abstract

The polypyrrole/basic oxygen furnace slag nanocomposite (PPy–BOFS) was synthesized and characterized by FTIR, SEM, ICP-AES, and X-ray diffraction studies and was employed as an adsorbent for the removal of phosphate ions from aqueous solution by the batch sorption method. The maximal amount of adsorption was found to be 9.13 mg/g (45°C). The Langmuir and Freundlich isotherms were used to describe the adsorption equilibrium. The kinetics of the adsorption process was investigated using the Lagergren rate equation and the Weber Morris intraparticle diffusion model. The FTIR and XRD pattern of the adsorbent before and after the adsorption was recorded to get better insight into the mechanism of the adsorption process. The results of equilibrium and spectral investigations revealed that the removal of phosphate by the nanocomposite involves various mechanisms followed by the nanocomposite and the constituents present in it.
