“…The presence of a peak located at ~1743 cm −1 indicated the presence of C=O stretching of the acetyl and uronic ester groups of polysaccharides, such as pectin, lignin, and hemicellulose [54,55]. The finding was almost similar to that reported by Ribeiro et al [56] in untreated mandarin peels, where the peak was located around ~1750 cm −1 . The p-coumeric acids of lignin and/or hemicellulosic acids were also linked to this peak [57].…”

The strict environmental regulations to overcome the drawbacks of consumption and disposal of non-renewable synthetic materials have motivated this investigation. The physical, chemical, morphological, and thermal properties of Hylocereus Polyrhizus peel (HPP) powder obtained from the raw materials were examined in this study. The physical properties analyzes of Hylocereus Polyrhizus peel (HPP) powder discovered that the moisture content, density, and water holding capacity were 9.70%, 0.45 g/cm 3 , and 98.60%, respectively. Meanwhile, the chemical composition analysis of Hylocereus Polyrhizus peel (HPP) powder revealed that the powder was significantly high in cellulose contents (34.35%) from other bio-peel wastes. The crystallinity index of Hylocereus Polyrhizus peel (HPP) powder was 32.76%, according to further X-ray diffraction (XRD) analysis. The thermal stability of Hylocereus Polyrhizus peel (HPP) powder was examined using thermogravimetric analysis (TGA) and found thermally stable at 204°C. The morphological study via scanning electron microscopy (SEM) showed a shriveled and irregular geometry surface. Hylocereus Polyrhizus peel (HPP) powder demonstrated the peak in the range representing the major functional groups responsible for pectin's properties. Thus, the findings revealed that the Hylocereus Polyrhizus peel (HPP) powder has the potential for the development of biodegradable and renewable materials.

“…This peak was also related to the p-coumeric acids of lignin and/or hemicellulose [23]. The existence of this shoulder was reported by Ribeiro et al [24] in untreated mandarin peels, where the presence of a peak located around ~1750 cm -1 indicates the presence of C=O streching which disappeared after treatment with a NaOH solution. Therefore, the absence of the peak from the spectrum (b) and (c) confirms the removal of the non-cellulosic materials from pomelo albedo.…”

Pomelo (Citrus grandis) peel is one of the under-utilized waste materials that have potential in the production of functional ingredients, due to its high fiber content. This study was conducted to isolate and characterize cellulose and nanocellulose from pomelo albedo. Cellulose was prepared via alkali treatment followed by bleaching process, while nanocellulose was produced via hydrolysis using sulfuric acid. The physicochemical and structural properties of the produced materials were characterized using proximate analysis, Fourier transform infrared spectroscopy (FTIR), and cellulose crystallinity index (CrI) by X-Ray Diffractometer (XRD) and water holding capacity (WHC). Proximate analysis showed that pomelo albedo contains 72.62% carbohydrate, 16.13% moisture, 6.27% protein, 3.41% ash and 1.56% fat. FTIR spectra for cellulose and nanocellulose confirms absorption bands characteristic of pure celluloses at 3334, 2902, 1630, 1427, 1030 and 896 cm-1. The crystallinity index (CrI) of the isolated nanocellulose was found considerably higher than that of cellulose with the value of 60.27% and 57.47%, respectively. Water holding capacity (WHC) of nanocellulose was also higher (p<0.05) than cellulose with the value of 12.75 g water/g and 8.9 g water/g respectively. We conclude that pomelo albedo can be a principal source of natural cellulose and nanocellulose materials which can be further manipulated for food ingredient applications.

“…All these compounds are rich in functional groups such as carboxyl and hydroxyl groups and therefore should have the ability to bind strongly to ionic species from aqueous solutions [25][26][27]. Mango peels were found to be a good adsorbent for the removal of toxic metals and organic substances from industrial wastewater [17], as well as banana peels [18,19], lemon peels [5], and tangerine peels [28,29]. In the case of tomato seeds and peels, there are few published data to date.…”

Removal of Pharmaceuticals from Water by Tomato Waste as Novel Promising Biosorbent: Equilibrium, Kinetics, and Thermodynamics

et al. 2021

Tomato waste was studied as a low-cost biosorbent for the removal of five pharmaceuticals (dexamethasone, febantel, procaine, praziquantel, and tylosin) from water. Tomato waste was characterized chemically and microstructurally before and after simulated sorption. Sorption performance was interpreted as a function of the initial pharmaceuticals concentration, temperature, and physicochemical properties of the tomato waste. The linear, Freundlich, and Dubinin–Radushkevich (D-R) isotherms were used to describe the experimental results at different temperatures (298, 303, and 308 K). Thermodynamic parameters such as standard free energy (ΔG°), enthalpy change (ΔH°), and entropy change (ΔS°) were determined. Negative values of ΔG° in the temperature range of 298–308 K strongly indicate the spontaneous nature of the biosorption process. In addition, the values of ΔH° for the biosorption of dexamethasone, procaine, praziquantel, and tylosin on tomato waste were negative, indicating exothermic processes, while the positive value for febantel indicated an endothermic process. The kinetic data were analyzed using (i) kinetic models to determine the kinetic parameters (Lagergren’s pseudo-first order and Ho’s pseudo-second order) and (ii) adsorption–diffusion models to the describe transport mechanisms of pharmaceuticals from aqueous solution onto tomato waste as adsorbent (Weber–Morris intraparticle diffusion and Boyd film diffusion models).
