Abstract
Polymer-based hybrid was widely fabricated and applied in heavy metal removal and other inorganic pollutants. The present study deals with the sorption efficiency of metal adsorption through the chemically modified PAA with dihydroxybenzenes into the polymeric matrix present in the tannery effluents and a parallel investigation of chromium (VI) ions in aqueous solution was carried out. From the Langmuir model the removal of chromium (VI) has the maximum adsorption capacity with 181.4mgg−1. Batch sorption to remove chromium (VI) and lead (II) from the tannery effluents was investigated by using different parameters. The sorption efficiency was found to be 75% and 99% for chromium (VI) and lead (II), respectively, present in the tannery effluents. The chemical and structural characteristics of the adsorbents were determined by UV, FT-IR, TGA, DSC, XRD and SEM-EDS analyses.
