“…Table 5 presents the values of the sorption capacities obtained for the biocarbons studied and the literature data for other adsorbents. According to Table 5 data, the biocarbons obtained from the residue of the extraction of chaga fungi ( Inonotus obliquus ) are superior relative to the parameters obtained for NaAlg-Chit/nZVI [ 34 ] and thiosemicarbazide modified chitosan [ 31 ]. The adsorbent NaAlg-Chit/nZVI [ 34 ] was obtained from iron nanoparticles and sodium alginate chitosan.…”

Biocarbons were obtained by physical and chemical activation of the residue of the extraction of chaga fungi (Inonotus obliquus). The residue was subjected to heat treatment carried out in a microwave oven and in a quartz tubular reactor. The materials were characterized by elemental analysis, low-temperature nitrogen adsorption, determination of pH, and the contents of acidic and basic oxygen functional groups on the surface of biocarbons by the Boehm method. The final biocarbon adsorbents have surface areas varying from 521–1004 m2/g. The physical activation of the precursor led to a strongly basic character of the surface. Chemical activation of Inonotus obliquus promoted the generation of acid functional groups. All biocarbons were used for methyl red sodium salt adsorption from the liquid phase. The sorption capacities of biocarbons towards the organic dye studied varied from 77 to 158 mg/g. The Langmuir model was found to better describe the experimental results. The results of the kinetic analysis showed that the adsorption of methyl red sodium salt on the biocarbons followed the pseudo-second-order model. The acidic environment was conducive to the adsorption of the dye on the obtained biocarbons. Moreover, thermodynamic studies confirmed that the organic dye adsorption on the biocarbons was a spontaneous endothermic process. The biocarbons obtained were also tested as adsorbents of hydrogen sulfide in dry and wet conditions. The sorption capacities towards hydrogen sulfide varied in the range of 21.9–77.9 mg. The results have shown that the adsorption of hydrogen sulfide depends on the process conditions and the activation procedure of biocarbons (method of activation and thermochemical treatment of samples). It has been shown that the initial material used can be a new precursor for obtaining cheap and—more importantly—universal bioadsorbents characterized by high effectiveness in the removal of air and water pollutants.

“…The process is carried out with rod magnets so that the adsorbent can be taken and reused repeatedly. The magnetic material used is Fe 3 O 4 that is synthesized by the coprecipitation method, which is a bottom-up method of making nanoparticles by involving NH 4 OH as the precipitating solution (Hu et al, 2020;Adusei et al, 2022). In this study, the adsorbent was carboxymethyl cellulose (CMC) nanoadsorbent which consisted of 3 types of materials, namely chitosan, magnetic Fe 3 O 4 , activated carbon from banana peel waste.…”

The development of nanoadsorbents for remediation of polluted water in order to obtain clean and healthy water quality has been carried out, namely the incorporation of chitosan, magnetic, and activated carbon materials. The activated carbon used is the result of the synthesis of banana peel waste nanocrystals, while the magnetic is Fe 3 O 4 . The method used in this study is an experimental method with coprecipitation through several stages, namely (1) magnetic synthesis of Fe 3 O 4 by thecoprecipitation method, (2) preparation of chitosan solution, (3) synthesis of activated carbon nanocrystals from banana peel waste by the milling process, (4) merger of the three materials, and (5) characterization with SEM/EDX, XRD, FTIR, BET, PSA, TGA, and AAS to test the performance of the material against polluted water. The study found that 210 minutes was the optimal time for the heavy metal ions Fe, Mn, Zn, and Pb to adsorption.The best sample was sample S4 with a ratio of 1:2:2 with adsorption for Zn 92.43%, Fe 95.44%, Mn 89.54%, and Pb 84.38%. For the heavy metal ions: Mn 5624 mg/g, Fe 5849.4 mg/g, Zn 4894.22 mg/g, and Pb 468.2 mg/g, the Langmuir model was used. The adsorption kinetics showed that the reaction order for Pb, Mn, Zn, and Fe ions varied with pseudo-first order and pseudo-second order. Carboxymethyl cellulose nanoadsorbents are effective in remediating the water contaminated with heavy metals, such as Pb, Mn, Zn, and Fe, meeting the environmental health quality standards for water media for sanitation hygiene purposes.

“…Wastewater treatment is an important field of study. Several techniques include: precipitation, ozonation, reverse osmosis, ion exchange, membrane filtration, electrochemical oxidation, coagulation, flocculation, and adsorption have been developed for the treatment of dye‐containing effluents 11–13 . However, most of these technologies are expensive and not highly efficient for the treatment of a wide range of dye containing wastewater 14–16 .…”

In this study, Tarbiat Modares University‐10/poly pyrrole (TMU‐10/PPy), a water‐stable metal–organic framework/polymer composite, was successfully fabricated and applied as adsorbent for removal of methyl red from contaminated water. The pyrrole obtained novel‐structured TMU‐10@PPy composite showed high efficiency in removing the methyl red. Several variables affecting the adsorption efficiency of methyl red, that is, pH, amount of adsorbent, contact times, and the salt additive, were investigated and optimized. The best working conditions were as follows: sample pH, 5; amount of sorbent, 4 mg; contact time, 9 min; salt additive, 2% (wt/vol). The maximum adsorption capacity of TMU‐10@PPy toward methyl red was 101.01 mg/g. The adsorption kinetics and isotherms of TMU‐10@PPy were consistent with a pseudo‐second‐order kinetic model and the Langmuir isotherm model. It was found that TMU‐10@PPy exhibited excellent reusability and had the potential for treating dye‐polluted wastewaters.
