“…In the FTIR spectrum of diatomite appeared to the bending vibration of Si-O-Si groups at 466 cm−1, symmetric stretching vibration at 795 cm−1 of Si-O groups, and asymmetric vibration at 1091 cm−1, of Si-O groups respectively. e band at 3453 cm −1 is attached to the stretching vibration of Si-OH groups [35,36]. In the FTIR spectra of CuCl-modified diatomites, the bands that are characteristic for diatomite were also observed.…”

An atomic implantation method was used to modify diatomite with CuCl. The CuCl/diatomite samples were characterized by different techniques, including FTIR, XRD, BET, SEM-TEM, EDX, and CO-TPR. Characterization results revealed the formation of CuCl particles of 50–60 nm highly dispersed on diatomite surface. CO adsorption measurements showed that 2CuCl/diatomite exhibits the highest CO adsorption capacity among all CuCl-modified samples with diatomite. Its CO adsorption capacity of 2.96 mmol/g at 30°C is 10 times higher than that of unmodified diatomite (0.29 mmol/g). The CO adsorption on CuCl-modified diatomites was found to fit well with the Langmuir–Freundlich model.

“…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.

“…The preparation was carried out at 298 K for 24h. The PANI@AC produced were filtered, washed with deionized water and then dried in oven at 343 K for 24h [25][26][27][28]. The pure PANI was synthetized in similar way mentioned above but in absence of AC.…”

By regeneration experiments after five cycles, acceptable results were observed.
