Abstract

In the present study adsorption of hazardous organic pollutants on activated carbon prepared from amla seed coats has been carried out in batch system. Phenol (P), o-cresol (OC), p-nitro phenol (PNP) and aniline (A) were selected as absorbates and activated carbon prepared from amla seed coats was used as an adsorbent. Activated carbon was prepared by physical activation in a specially designed high temperature activation system (HTAS). Prepared activated carbon was characterized by proximate and ultimate analysis, Iodine value, N2-BET surface area, pore volume, scanning electron microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FT-IR). SEM analysis of the carbon reveals the presence of macro-, meso- and micro-pores, crakes and crevices. FT-IR spectrum shows the presence of various surface groups with a predominant presence of phenolic-OH group. The adsorption studies infer that the substituted phenols adsorb more than the phenol itself as the adsorption capacity for p-nitro phenol is more than other phenols studied. Solubility of the adsorbate also plays an important role in adsorption as more hydrophobic p-nitro phenol adsorbs more than less hydrophobic phenol, o-cresol and aniline.
