From agricultural wastes to a resource: Kiwi Peels, as long-lasting, recyclable adsorbent, to remove emerging pollutants from water. The case of Ciprofloxacin removal

Recent advances in carbon-based nanomaterials for the treatment of toxic inorganic pollutants in wastewater

“…Therefore, nanomembranes help to remove all types of pollutant, and thus are a prominent technique for removal processes. 101 Metal-oxide nanoparticles act as a catalyst for oxidation reactions that remove many impurities from water by photocatalytic reactions. Organic pollutants, inorganic pollutants, dyes, and pesticides can be treated using doped nanoparticles, where the pollutant removal ratio compares with other nanocomposites.…”

Kiwi peel waste as a recyclable adsorbent to remove textile dyes from water: Direct Blue 78 removal and recovery

“…Indeed, some authors of this paper recently have reported the use of this waste/adsorbent for the removal of emerging pollutants, presenting for the first time the chemical and physical features of kiwi peels. 34,35 In particular, Gubitosa et al, 34,35 by the synergistic use of different techniques (such as SEM investigation, FTIR-ATR, and TG analyses), showed that the adsorbent is characterized by particular morphological features, irregular domains, and filaments on both sides of peels' surfaces, and it is mainly constituted by lignin, cellulose, and hemicellulose. Furthermore, it was demonstrated that the main morphological and chemical features of kiwi peels were also retained after their use and reuse during the adsorption/ desorption processes, enabling kiwi peels as a long-lasting adsorbent material.…”

“…Furthermore, it was demonstrated that the main morphological and chemical features of kiwi peels were also retained after their use and reuse during the adsorption/ desorption processes, enabling kiwi peels as a long-lasting adsorbent material. 34,35 This work aims to widen the kiwi peels' applicability, proposing that this waste can also be used for the anionic textile dye removal from water. Indeed, about this concern, only one work is reported in the literature, and it refers to methylene blue and rhodamine B removal.…”

“…36 On the other hand, kiwi peels, to our knowledge, were employed in the past to remove Cd 2+ , Cr 3+ and Zn 2+ ions, 37 nitrate, 38 and oil, 39 sequester Pb 2+ , 40 and, as previously said, to remove emerging pollutants. 34,35 Therefore, a deep scientific research activity should be developed to promote the sustainable management of kiwi peels' wastes to address environmental problems related to dye pollution. Moreover, an important aspect of this paper is related to the eco-friendly kiwi peel pre-treatment, avoiding hard experimental conditions and hazardous materials, as already reported by Gubitosa et al 34,35 Furthermore, the adsorbent recycling was proposed under safe conditions, demonstrating the dyestuff reuse.…”

Consumer‐oriented intelligent ripening control system for post‐ripening fruit

“…Chemical ripening involves the use of chemicals that release ethylene (Li et al, 2022). Physical ripening techniques include high irradiance treatment of tomatoes, changing the storage temperature of kiwis, and treating bananas at different temperatures (Cheng et al, 2022; Gubitosa et al, 2022; Steelheart et al, 2022). The results of these studies showed that high light and high temperature accelerated the ripening rate of fruits.…”
