“…The occurrence of unconjugated carbonyl (C=O), imine (C=C) and C-O functionalities is indicated by vibrations at 1745, 1609, and 1045 cm −1 , respectively. The presence of small peaks in the spectral area between the C-O and C=C, corresponds to bending peaks of -CH 3 group [ 34 , 36 ]. The band at 514–708 cm −1 proved the existence of –OH polysaccharide groups.…”

“…However, for the present, there is a rising demand to discover effortlessly obtainable, highly efficient, and very cost effective adsorbents for the adsorption of Cu(II) ions from different matrices. Cashew nut shell [ 5 ], saw dust [ 29 ], spent grain [ 30 ], wheat straw [ 31 ], pine cone powder [ 32 ], sawdust [ 33 ], herbaceous peat [ 34 ], peanut hull [ 6 ] sugar beet pulp [ 35 ], and others [ 36 , 37 , 38 , 39 ] are examples of effective adsorbents to remove copper ions. Due to the great obtainability and low-price of these adsorbents a complex regeneration method is not needed, and this cheaper adsorption system has involved numerous researchers.…”

“…Several investigational parameters, including solution contact time, pH, starting concentration, and Cu(II) ion temperature, were also studied. Langmuir and Freundlich adsorption isotherms were applied to study the equilibrium modelling [ 36 ]. Thermodynamic and kinetic characteristics have been applied to assess the nature of the sorption method.…”

In the current study we prepared cost-effective adsorbents based on ajwa date pits to remove Cu(II) ions from aqueous medium. Adsorbents were studied using scanning electron microscopy (SEM), FT-IR, and Brunauer-Emmett-Teller (BET) methods to characterize the surface functionalities, morphology, pore size, and particle size. The concentration of Cu(II) ions in the studied samples was determined by atomic adsorption spectrometry technique (AAS). Adsorption method was performed sequentially in a batch system followed by optimization by studying the numerous conditions, for instance the initial amounts of Cu(II) ions, dosages of the adsorbent, contact time, and pH of the solution. The ideal pH observed for maximum adsorption capacity was ~6.5. Langmuir and Freundlich isotherm models correctly predicted the investigation results, with the maximum monolayer adsorption capacities for Cu(II) ions at 328 K being 1428.57 mg/g (treated ajwa date pits, TADP) and 1111.1 mg/g for as produced ajwa date pits (ADP). It was revealed that TADP possess greater adsorption capability than ADP. Recovery investigations revealed that the saturated adsorbents eluted the maximum metal with 0.1 M HCl. Cu(II) ions adsorption was observed to be reduced by 80–89% after the second regeneration cycle. For the raw and chemically processed ajwa date pits adsorbent, the Langmuir model performed significantly better than the Freundlich model. The results demonstrated that the adsorbent made from ajwa date pits could be an economical and environmentally friendly alternative for removing Cu(II) ion pollutant from aqueous media.

“…Individual desirability (di) values between 0 and 1 are first created for each individual response in this method. A desirability value of 1 generally means that the targeted level of response was attained, whereas a desirability value of 0 means that the desired level of reaction was surpassed [ 3 ]. The following Equation (6) is used to determine the total desirability function.…”

In this study, Mango (Mangifera indica) seeds (MS) and peels (MP) seeds mixed fruit wastes were employed as a renewable precursor to synthesize high-surface-area-activated carbon (MSMPAC) by using microwave-induced ZnCl2 activation. Thus, the applicability of MSMPAC was evaluated towards the removal of cationic dye (methylene blue, MB) from an aqueous environment. The key adsorption factors, namely A: MSMPAC dose (0.02–0.1 g), B: pH (4–10), and C: time (5–15 min), were inspected using the desirability function of the Box-Behnken design (BBD). Thus, the adsorption isotherm data were found to correspond well with the Langmuir model with a maximum adsorption capacity of (232.8 mg/g). Moreover, the adsorption kinetics were consistent with both pseudo-first-order and pseudo-second-order models. The spontaneous and endothermic nature of MB adsorption on the MSMPAC surface could be inferred from the negative ∆G° values and positive value of ∆H°, respectively. Various mechanisms namely electrostatic forces, pore filling, π-π stacking, and H-bonding govern MB adsorption by the MSMPAC. This study demonstrates the utility of MS and MP as renewable precursors to produce high-surface area MSMPAC with a potential application towards the removal of cationic organic dyes such as MB.

Immobilization of biogenic silver–copper nanoparticles over arylated biochar from sugarcane bagasse: Method and catalytic performance

There is an ever‐growing demand for biochar production and its chemical transformation into specialty materials. Herein, we suggest a versatile method to elaborate Ag/Cu nanoparticles, by phytochemical process, on aryl‐sulfonated sugarcane bagasse pulp‐derived biochar. A binary nanocomposite has been fabricated through a four‐step strategy. The raw substrate biochar was first prepared by a slow pyrolysis of the biomass at 500°C under N2:H2 95%:5% inert atmosphere. Thereafter, in situ arylation of the biochar surface has been performed to obtain SO3H‐Biochar. The loading of silver and copper ions on SO3H‐Biochar has been achieved via a wet impregnation using a hydroalcoholic medium. Finally, the natural extract obtained from sugarcane bagasse has been employed to ensure the reduction of the adsorbed metal ions and obtain SO3H‐Biochar@Ag/Cu. Interestingly, the structural analysis of SO3H‐Biochar@Ag/Cu and the study of the evolution of D to G band intensity and area ratios have revealed that the metal phase deposition has altered the SO3H‐Biochar surface properties. It finally provided a more graphitized nanocomposite compared with the bare biochar and the intermediate substrate (SO3H‐Biochar). Such a result suggests that the phytochemical reduction has catalyzed the substrate graphitization. The catalytic performance of SO3H‐Biochar@Ag/Cu has been investigated in the oxidative degradation of malachite green oxalate. A total mineralization of the dye has been registered, and the experimental data were found to give a best fitting to the pseudo‐first‐order model. The fitting was relatively good with a mineralization apparent constant rate equals to 65 10−3 min−1. It is worth mentioning that all experiments used a relatively low amount of the composite catalyst (2.5 mg). So to recap, this route takes advantage of the two phases of sugarcane bagasse to generate a robust biochar‐based catalyst, its solid phase to derive biochar substrate with particular properties, and its liquid extract to be used as natural reducing preparation.
