Abstract

Aniline is a toxic chemical compound and one of the common pollutants found in the effluents from the pharmaceutical, pesticide, dyestuff, petrochemicals and agrochemical industries. The aim of this study was to investigate the sorption of aniline using Aloe Vera wastes-based activated carbon (AV-AC) from water. In this batch study, the effects of various factors including contact time, pH, adsorbent dosage and initial aniline concentrations were surveyed on the aniline sorption. The results illustrated that the optimum pH and contact time for the removal of aniline by AV-AC was obtained at 3 and 60 min, respectively. The decrease of pH had a significant influence on the increasing aniline adsorption. Fitting the experimental data to various kinetics and isotherms models showed that the experimental data were better descripted by pseudo-second order and Freundlich models, respectively. Because of low-cost, eco-friendly, non-toxicity and high sorption capacity, this sorbent can be used as a very effective option to removal of aniline from aqueous media.
