“…The initial peak at 279 nm (CTS-AA) blue-shifted to 270 and 275 nm, corresponding to CTS-AA-Bi and CTS-AA-Zr, respectively. More so, the weak absorption peak at 335 nm in CTS-AA was also blue-shifted hyperchromically to 328 nm with CTS-AA-Zr, thus confirming the formation of ZrNPs (Figure a). , …”

The introduction of the metals was accompanied by a wide hyperchromic red shift to 228 nm.…”

In this work, chitosan in citric acid and ascorbic acid along with glucose solutions served as stabilizing and reducing agents of Bi and Zr nanometallic particles, respectively, to produce chitosan-ascorbic acid-bismuth/zirconium (CTS-AA-Bi)/(CTS-AA-Zi), and chitosan-citric acid-bismuth/zirconium (CTS-CA-Bi)/(CTS-CA-Zr) materials. Scanning electron microscopy (SEM) images revealed an irregular sheet-like and round-shaped morphologies attributed to CTS-AA-Bi and CTS-AA-Zr, respectively, with slight agglomeration. Moreover, the high-resolution transmission electron microscopy (HR-TEM) image confirmed the monoclinic polynanocrystalline phase of the materials as revealed by X-ray diffraction (XRD) with an average particle size of 76 nm. The as-prepared materials displayed significant antifungal activity against Botrytis cinerea, plausibly due to the sustainable release and attachment of Zr ions to the fungal cells, thereby generating pores on the cell, damaging the cell wall/membranes, and leading to cell death. A substantial antifungal effect was also observed with postharvested cherry fruits sprayed up to 10 d. This new nanoagrofungicide can be used to preserve postharvested fruits and vegetables against fungi attack.

“…AOPs are highly efficient in the removal of color and organic matter; however, the complete mineralization of contaminants represents an increase in the carbon footprint of the process contributing to global warming (Vidya Lekshmi, Yesodharan and Yesodharan, 2018 ; Oriol et al 2019 ; Vorontsov 2019 ; Nguyen et al 2020 ; Wang and Zhu 2020 ). Therefore, for the mineralization of organic matter into CO 2 , some strategies for its capture (in the form of and ) are recommended, such as photocatalysis and electrooxidation (Shinde, Patil, G. Do Kim, et al 2020 ) (Fig. 9 b).…”

The denim textile industry represents an important productive sector. It generates wastewater with low biodegradability due to the presence of persistent pollutants, which can produce toxic and carcinogenic compounds; therefore, wastewater treatment reduces risks to aquatic life and public health. This paper presents a review of 172 papers regarding textile industry wastewater treatment for the removal of contaminants, especially indigo dyes used in the denim industry, in the context of green technologies. The physicochemical characteristics of textile wastewater, its environmental and health impacts, and the permissible limit regulations in different countries were reviewed. Biological, physicochemical and advanced oxidation processes for the removal of indigo dyes were reviewed. The goal of this study was to analyze the characteristics of green technologies; however, the research does not clearly demonstrate an effect on energy consumption savings, carbon footprint decreases, and/or waste generation. Advanced oxidation processes showed the highest color removal efficiency (95 and 97% in synthetic or real wastewater, respectively). Photocatalysis and Fenton reactions were the most efficient processes. None of the revised works presented results regarding upscaling for industrial application, and the results should be discussed in terms of the guidelines and maximum permissible limits established by international legislation. New technologies need to be developed and evaluated in a sustainable context with real wastewater.
