“…The microscopic pore structure property of AC sample was characterized by physical adsorption of gases (nitrogen at 77K & Carbon dioxide at 273K) using Micromeritics ASAP-2020M system. Correspondingly, N 2 adsorption is mainly to gain the information on total micropores volume (V DR ) applying the Dubinin-Radushkevich (DR) formula and to determine the speci c surface area according to the BET law (S BET ) [20,27].…”

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.

“…Several synthesis methods have been widely used for the synthesis of the hybrid materials of PANI with ZnO [17]. Additionally, PANI@inorganic hybrid is already an established adsorbent of organic pollutants in aqueous solution, such as Orange G, Methyl orange, Methylene blue, Malachite green, Congo red, Amido black 10B [25][26][27][28][29], etc. This investigation aims to demonstrate the synthesis and application of PANI@ZnO by in-situ chemical oxidative process.…”

In this research, a simple oxidation chemical process was applied for the synthesis of novel PANI@ZnO nanocomposite. The prepared nanocomposites were characterized by XPS, XRD, FTIR, SEM, TGA and N2 adsorption-desorption isotherms. Thereby, PANI@ZnO highest SBET values (about 40.84 m 2 .g −1 ), total mesoporous volume (about 3.214 cm 3 .g −1 ) and average pore size (about 46.12 nm). Afterwards, the prepared nanomaterial was applied as novel nanoadsorbent for the adsorption of Congo Red (CR) and Methylene Blue (MB) dyes from aqueous solutions at 298 K and pH 5.0. Besides, the pseudo-second-order model was obtained the best for the adsorption of both dyes. In the case of isotherm models, the Freundlich model showed the best fit. After removal, the spent adsorbent was regenerated. With the regeneration repeated five cycles, the PANI@ZnO regeneration efficiency remained at a very adequate level.

The aim of this work is to investigate the adsorption performance of orange G (OG) dye from aqueous solutions employing PANI@sawdust biocomposite enrobed by calcium-alginate biobeads (Alg-PANI@SD). The as-prepared adsorbent was characterized by scanning-electron-microscopy (SEM), X-ray energy dispersive spectroscopy (EDS) and Fourier transforms infrared (FT-IR) spectroscopy, and used to remove Orange G dye from water. batch tests were performed as a function of adsorbent dosage, pH, contact time, interfering ions and initial OG dye concentration. Experimental results show that the kinetic model of pseudo-first-order (PFO) and Freundlich isotherm provided a good fitting of the whole experimental data. The results revealed that the as-prepared tricomposite Alg-PANI@SD, has the potential to be applied as a low-cost adsorbent for the adsorption of OG dye from aqueous media.
