Abstract
In the current article, an azo dye adsorbent was prepared by using Parthenium flowers activated carbon (PFAC). Sulphuric acid (H2SO4) was utilized as an activator for the preparation of activated carbon from a biomass solid waste, parthenium flowers. The sulphuric acid-treated activated carbon (PFAC) was used as low-cost adsorbent for the removal of Eriochrom black-T (EBT) azo dye from aqueous solution. The prepared activated carbon was characterized by Fourier transform infrared spectroscopy (FT-IR) before and after the adsorption process and scanning electron microscopy (SEM). A FT-IR spectrum the various functional groups present in the PFAC. SEM micrographs show the rough and irregular along with heterogeneous cavities that well distributed across the PFAC surface. Morphology of the product which is irregular shape and uniformly distributed. Adsorption property of PFAC against EBT was examined by considering the dosage effect, effect of pH, stirring time and varying concentration. At neutral pH, 10 ppm EBT azo dye aqueous solution adsorbed on PFAC (92%). Batch adsorption and regeneration studies were studied.
