Article Abstract
The recycling of copper and nickel from metallurgical wastewater using emulsion liquid membrane (ELM) was studied. P507 (2-ethylhexyl phosphonic acid-2-ethylhexyl ester) and TBP (tributyl phosphate) were used as carriers for the extraction of copper and nickel by ELMs, respectively. The influence of four emulsion composition variables, namely, the internal phase volume fraction (ϕ), surfactant concentration (Wsurf), internal phase stripping acid concentration (Cio) and the carrier concentration (Cc), and the process variable treat ratio on the extraction efficiencies of copper or nickel were studied. Under the optimum conditions, 98% copper and nickel were recycled by using ELM. The results indicated that ELM extraction is a promising industrial application technology to retrieve valuable metals in low concentration metallurgical wastewater.

This exploratory study surveyed seven contaminated brownfields and Superfund sites in Southern California to identify locally adapted species tolerant of mixed organic and metal contamination under arid and semi-arid conditions. Five novel native plants, including Brickellia californica, Baccharis salicifolia, Baccharis sarothroides, Eriogonum fasciculatum, and Heterotheca grandiflora were identified as hyperaccumulators of copper (Cu), alongside a non-native species from the Asteraceae family, Helminthotheca echioides. Additional metal-accumulating plants (including native plants) for lead (Pb), chromium (Cr), arsenic (As), and nickel (Ni) were identified, and warrant further evaluation for their phytoremediation potential.

The Natural Resistance Associated Macrophage Proteins (NRAMPs) are membrane-targeted transporters with low substrate specificity, that mediate the import (translocation to the cytoplasm) of metals, mainly essential nutrients, e.g. iron (Fe), manganese (Mn), zinc (Zn), cobalt (Co), copper (Cu) or nickel (Ni).

An α-aryl-substituted enantioenriched ketone is a valuable building block for the production of both natural and medicinal compounds. Research into their asymmetric synthesis can be challenging yet rewarding because of the need to control regio-, chemo-, and enantioselectivity carefully. A wide range of catalytic strategies has been developed during the past three decades to gain access to these favored motifs.

Bioaccumulation of metals and metalloids in marine environments poses a significant risk to both human and aquatic health, with seasonal fluctuations substantially influencing its dynamics and magnitude. This study investigated the impact of metals and metalloids exposure on the health of Wallago attu (Wallago catfish) and Catla catla (Indian carp) inhabiting the Head Siphon, Mailsi, Pakistan. This study involved the seasonal (May 2022, October 2022, April 2023) assessment of physicochemical properties and the concentrations of several metals and metalloids-copper (Cu), chromium (Cr), arsenic (As), cadmium (Cd), nickel (Ni), zinc (Zn), and iron (Fe)-in water samples.

The stabilization of metal nanoparticles is a key factor in various applications, but its wide use requires the development of effective and advanced materials. For the first time, this work demonstrates that in situ self-assembly of copper (Cu) and nickel (Ni) nanoparticles (NPs) via chitosan (Ct) allowed the formation of a new matrix Cu-Ct-Ni. The obtained Cu-Ct-Ni matrix was fully characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and UV-vis.
