![]() It is also a common byproduct of the paper and textile industries. in the manufacture of dyes, rubbers, pharmaceutical preparation, plastic and paint. The pseudo-second-order kinetic equation could better describe the kinetic behavior of aniline adsorption.Īniline is frequently used as a raw material by the chemical industry, i.e. The Freundlich model exhibited better correlation of the equilibrium adsorption data. This adsorbent allowed high removal toward aniline in a wide range of pH. These results showed that the optimum operating conditions were: the ratio of AC to chitosan = 0.5, adsorbent dosage = 0.2 g, and the adsorption of aniline from aqueous solutions had better removal in the concentration range of 20–50 mg/L. The factors affecting the adsorption of aniline onto AC coated by chitosan, including the ratio of AC to chitosan, adsorbent dosage, pH value of solution, initial aniline concentration, and contact time were evaluated. ![]() The removal of aniline from aqueous solutions by AC coated by chitosan was investigated. ![]() In this work, activated carbon (AC) coated by chitosan was synthesized and characterized by Fourier transform infrared spectrophotometer and scanning electron microscope (SEM) techniques. ![]()
