This work investigated the elimination of Methyl Orange (MO) using a new adsorbent prepared from Activated Carbon (AC) with polyaniline reinforced by a simple oxidation chemical method. The prepared materials were characterized using XRD, TGA, FTIR and nitrogen adsorption isotherms. Furthermore, PANI@CA highest speci c surface area values (near 332 m 2 .g − 1 ) and total mesoporous volume (near 0.038 cm 3 .g − 1 ) displayed the better MO removal capacity (192.52 mg.g − 1 at 298 K and pH 6.0), which is outstandingly higher than that of PANI (46.82 mg.g − 1 ). Besides, the process's adsorption, kinetics, and isothermal analysis were examined using various variables such as pH, MO concentration and contact time. To pretend the adsorption kinetics, various kinetics models, the pseudo rst-and pseudo secondorders, were exercised to the experimental results. The kinetic analysis revealed that the pseudo second order rate law performed better than the pseudo rst order rate law in promoting the formation of the chemisorption phase. In the case of isothermal studies, an analysis of measured correlation coe cient (R 2 ) values showed that the Langmuir model was a better match to experimental results than the Freundlich model. By regeneration experiments after ve cycles, acceptable results were observed.

“…In recent years, conjugated polymers, particularly those based on polyaniline (PANI), polythiophene (PT) and their derivatives, have gained popularity as chemical adsorbents because of multiple properties such as the low cost synthesis and their numerous applications in rechargeable batteries, display devices and sensors, porous structure, tunable morphology, good electrorheological property, unique redox chemistry, non-toxicity, insolubility in water and reversible ions sorption and desorption capability, environmental stability, their simple doping and dedoping by acid/base treatment have made them very interesting agents in conducting polymers family [4][5][6][7][8][9][10].…”

Conducting Polymeric composites have attracted great attention over the last years because of their potential uses in chemical, electronic and optical devices, and as catalysts as well as in adsorption processes. Chemical synthesis of polyaniline (PANI) and polyaniline-SiO2 composite and their adsorptive performance were reported in the present work. These materials were prepared and evaluated for their methylene blue (MB) dye adsorption characteristics from aqueous solution. Adsorption equilibrium kinetic and thermodynamic experiments of MB onto PANI and PANI/SiO2 were studied. The effects of initial dye concentration, contact time and temperature on the adsorption capacity of PANI/SiO2 for MB have been investigated. The pseudo-first order and pseudo-second order kinetic models were used to describe the kinetic data. It was found that adsorption kinetics followed the pseudo-second order at all of the studied temperatures. The Langmuir, Freundlich and Dubinin Raduschkevich adsorption models were used for the mathematical description and the fit obtained using the Dubinin Raduschkevich isotherm has a medium R2 value.
