    Abstract According to circular bioeconomy principles, the use of kiwi peels to remove Direct Blue 78 (DB) from water is investigated during this work, proposing food waste as a recyclable adsorbent substrate. Direct Blue 78 (DB) was adopted as a model pollutant, employing its visible spectrum to monitor its adsorption. The adsorption process was thus fully characterized, investigating the roles of ionic strength, pH values, adsorbent/pollutant amounts, and temperature. The thermodynamics, kinetics, and adsorption isotherms were also studied. To extend the kiwi peels' lifetime, quite complete desorption was obtained by adopting hot water as a safe and eco-friendly strategy. Despite the relatively low kiwi peels' maximum adsorption capacity (6 mg g

    Abstract Due to the pollution problem, the use of more sustainable materials with a reduced environmental impact, spanning across biocompatible and biodegradable polymers, is growing worldwide in many different fields, particularly when referring to applications in Life Sciences. Accordingly, with the aim of developing multifunctional materials for potential cosmetic/biomedical purposes, this work reports the physical and chemical characterization of chitosan-based films blended with snail slime, exhibiting antioxidant and sunscreen features. A suitable formulation for preparing free-standing chitosan platforms, mixing low molecular weight chitosan, lactic acid, glycerol, and snail slime into an appropriate ratio, is thus described. The results obtained by morphological analysis and ATR-FTIR spectroscopy, XRD, swelling analysis (also when varying pH, ionic strength, and temperature), and WVTR measurements evidence a uniform distribution of snail slime inside the chitosan network, forming more compacted structures. At first, the UV-Vis analysis is used to investigate the theoretical Sun Protection Factor, finding that these innovative platforms can be used for preventing sunburn. Then, the antioxidant features are investigated using the ABTS assay, displaying a snail slime-mediated and dose-dependent boosted activity.

    Abstract This work accounts for the first example of dry Kiwi Peels to remove emerging pollutants from water. Both the inner and outer sides of Kiwi Peels were characterized by using in synergy FTIR-ATR, TG, and SEM analyses before and after its use and re-use, proposing it as long-lasting, recyclable adsorbent material. Among the tested 14 emerging pollutants, 6 of them were successfully removed by Kiwi Peels, also if present in mixtures, calculating the Kiwi Peels maximum adsorption capacities, occurring in the range of 1–4 mg/g. To infer information about the behavior of Kiwi Peels during water treatments, Ciprofloxacin, a well-known and largely used antibiotic, was selected as a dangerous model contaminant. The roles of ionic strength, pH values, adsorbent/pollutant amounts, and temperature values during the adsorption process were assessed, giving physical and chemical information about the whole adsorption process. The thermodynamics, the adsorption isotherms, and kinetics were studied. The Freundlich model, with a good correlation, well described the obtained results, indicating the heterogenous character of the Ciprofloxacin adsorption with the formation of a multilayer of pollutant molecules onto the adsorbent surface. If, on the one hand, in the range of temperatures 283–303 K, the Ciprofloxacin adsorption was favored by increasing the temperature, on the other hand, the adsorption was hindered by further incrementing of temperature due to the pollutant desorption. Until the occurrence of desorption, the process occurred with ΔH° and ΔS° > 0 with a ΔG° < 0. Both the pseudo-first and pseudo-second-order kinetic equations seemed to describe the process with the applicability of the Weber-Morris model. The results suggested the main presence of electrostatic interaction between the pollutant and adsorbent by changing the pH values and ionic strength of Ciprofloxacin solutions. As a whole, from the obtained results, the best condition to remove Ciprofloxacin is neutral pH in the absence of salt at 303 K. The Kiwi Peels and Ciprofloxacin recycling was also investigated by performing desorption experiments using 0.1 M MgCl₂ solution, increasing the Kiwi Peels maximum adsorption capacity at least from 4 to 40 mg/g for Ciprofloxacin. At least 10 cycles of adsorption/desorption were performed, desorbing almost 75% of adsorbed pollutants during each run. Preliminary information about the possibility of inducing the solid-state pollutant photodegradation by using Advanced Oxidation Processes was also explored, giving a possible alternative for pollutant desorption and adsorbent recycling.

    Abstract Due to their properties, snail slime-based products have been appreciated and used worldwide. So, as an alternative and innovative use of snail slime, it was adopted to induce gold nanoparticles' formation, conferring them interesting properties. By a simple, one-pot, and eco-friendly approach, 14 ± 6 nm wide hybrid gold nanoparticles, having an inorganic metallic core decorated by the slime's main components, were obtained. Among their several properties, their antioxidant and tyrosinase inhibition activity were investigated through the DPPH and ABTS and the tyrosinase assays, respectively. After assessing their non-cytotoxicity in our previous work, the results revealed positive responses, enabling their use as a potential novel multifunctional ingredient in cosmetics. Interestingly, the gold nanoparticle photostability, investigated by means of a solar simulator lamp, suggests using them in commercial cosmetic sunscreen products as a potential alternative to the commonly used inorganic sunscreen ingredients. The theoretical Sun Protection Factor was evaluated, obtaining values in the range 0–12. The proposed environmentally friendly and cost-effective protocol for nanoparticle synthesis, following the principles of Green Chemistry, opens a hugely attractive space toward the study of snail slime-based gold nanoparticles as a potential multipurpose platform in cosmetics.

    Abstract Amino-grafted Mobil Composition of Matter N. 41 (MCM-41/NH₂) and Santa Barbara Amorphous (SBA-15/NH₂) type mesoporous adsorbents were successfully used and compared in this work to remove azo dyes (and their mixture) from highly colored solutions. This paper reports a very fast removal and recycle (in 5 min) of great amounts of textile dyes (about the 100%) by materials characterized by high adsorption/desorption capacities. A qₘₐₓ ≈ 250 mg/g for each adsorption cycle, that should be potentially increase to ≈ 1250 mg/g, under appropriate experimental conditions, was found for the proposed adsorbents. The UV–Vis absorption spectra of dyes were used to support this finding, determining the rate of adsorption. Several parameters affecting the adsorption process were investigated: the contact time, dyes solution pH values and amount of the adsorbent materials, ranging from 0.4 mg to 12 mg, and dyes (5 × 10⁻⁵ M and 1 × 10⁻⁵ M). Further, the Nitrogen adsorption/desorption isotherms, SAXS patterns, TG analyses, Zeta-potential measurements and microscopic imaging techniques, such as SEM and TEM, were used to detail the nature of interaction between dyes and adsorbents, and to investigate the morphology and the mesoporous array of the amino grafted MCM-41 and SBA-15.

    Abstract The aim of this paper is to present and characterize Polyamidoamine-based hydrogels (PAA) as scaffolds to host photoactive Chlorophyll a (Chl a) from Spirulina (Arthrospira platensis) sea-weed Extract (SE), for potential applications in Photodynamic Therapy (PDT). The pigment extracted from SE was blended inside PAA without further purification, according to Green Chemistry principles. A comprehensive investigation of this hybrid platform, PAA/SE-based, was thus performed in our laboratory and, by means of Visible absorption and emission spectroscopies, the Chl a features, stability and photoactivity were studied. The obtained results evidenced the presence of two main Chl a forms, monomeric and dimeric, interacting with hydrogel polyamidoamines network. To better understand the nature of this interaction, the spectroscopic investigation of this system was performed both before and after the solidification of the hydrogel, that occurred at least in 24 h. Then, focusing the attention on solid scaffold, the
