“…Higher initial dye concentrations resulted in increased adsorption capacities, as more dye molecules were present near each unit mass of adsorbent, facilitating a faster adsorption rate . Conversely, lower initial dye concentrations led to fewer dye molecules surrounding each unit mass of adsorbent, resulting in the adsorption of a smaller number of dye molecules . Specifically, the adsorption capacity of CV and MO by TKC-Ni 0 NPs increased from 135.00 to 603.75 mg/g and from 180.00 to 646.50 mg/g as the initial dye concentrations were raised from 10 to 150 mg/L.…”

In this study, a novel biobased treated kaolin clay incorporated with zerovalent nickel (TKC-Ni 0 NPs) was fabricated and employed as an efficient functionalized adsorbent for the elimination of crystal violet (CV) and methyl orange (MO) from textile wastewater. The adsorption capacity of TKC-Ni 0 NPs was improved by incorporating the functional moieties of nickel nanoparticles on the treated kaolin clay structure using the experimental data from the kinetics, isotherm, thermodynamics, and reusability study. The crystalline structures, functional groups, and morphological characteristics of TKC, Ni 0 NPs, and TKC-Ni 0 NPs were analyzed using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and high-resolution scanning electron microscopy (HRSEM). The point of zero charge pH on the surface of the TKC-Ni 0 NPs was evaluated as 4.5. The adsorptive removal of CV and MO was explored at solution pH, contact time, adsorbent dosage, initial CV/MO concentration, and temperature. Maximum adsorption capacities of 802.56 and 812.28 mg/g were reported for both CV and MO using TKC-Ni 0 NPs at the optimal solution pH of 6 for CV and 4 for MO, contact time of 60 min, adsorbent dosage of 25 mg/L, initial CV/MO concentration of 100 mg/L, and temperature of 313 K. Remarkably, TKC-Ni 0 NPs exhibited favorable behavior for the adsorption of MO and CV in the presence of both cationic and anionic coexisting ions. The reusability study showed over 92.00 and 94.00% effectiveness for CV and MO even after 10 cycles, respectively, which holds great promise for industrial use. A pseudo-second-order kinetic model effectively suited the adsorption kinetics, implying that the adsorption process is chemisorption controlled. Among the explored isotherm models, the Langmuir isotherm model exhibited the best fit for the experimental data. Thermodynamic analysis indicated that the adsorption is endothermic and spontaneous on the adsorbent surface. Consequently, a cost-effective, versatile, and stable biobased composite with significant potential for industrial wastewater treatment was successfully developed.

“…Particularly, banana peels in powder form were examined as adsorbents for removing MB dye and pesticides, such as glyphosate and atrazine [28], or chlorpyrifos by lemon peels [29], from water. In addition, other kind of peels, such as orange, pomegranate, kiwi, etc., have been found to be effective for removing several dyes from wastewaters [30,31] and pharmaceuticals [32]. In recent literature, Artocarpus genus fruit peels were also examined as raw peels or as biomass for activated carbon production for the removal of various pollutants present in aqueous streams [33].…”

Wastewater treatment has attracted much attention in recent years as a potential source of water, and there are some concerns about its safety for human use. Eco-friendly and cost-effective adsorbent materials were successfully synthesized from several peels, such as orange, banana, pomegranate, avocado, kiwi, etc., and were used as natural adsorbents or as activated carbons derived from these peels for water and wastewater treatment. In this review, the latest research focusing on the effective modification of these peels for the removal of several pollutants found in wastewaters are summarized and compared, such as pharmaceuticals, dyes, heavy metals, and anions that are released in waste and have a negative impact on human and animal health. In this review, focus is given to activated carbon produced from fruit peels. Moreover, fruit peels as adsorbent materials, without previously being converted to activated carbon, are of limited use in the recent literature.
