“…6,8 The world consumes over 800 000 tons of organic dyes annually, where approximately 20% of the total dyes production is wasted during various industrial dying processes. [9][10][11] Effluents resulting from the textile and dyeing industries process usually contain mixtures of dyes, metal ions, and other pollutants, as well as to its elevated levels of biochemical oxygen demand, pH, suspended solids, chemical oxygen demand, salts, and colors. 6 The discharge of these pollutants into bodies of water without proper treatment can have serious consequences, such as toxicity to mammals, sh, and aquatic microorganisms, and can even obstruct the photosynthesis of aquatic plants, resulting in the destruction of the aquatic ecosystem.…”

To address sustainability issues, the green synthesis of nanomaterials has recently received considerable attention. This article addresses a novel and cost‐effective adsorbent for the extraction of eight phenyl‐N‐methylcarbamate insecticides from water samples. We first synthesized a magnetite/hydroxyapatite nanocomposite using snail shell powder via an environmental friendly approach. The morphology and physicochemical properties of magnetic hydroxyapatite were characterized by Fourier transform infrared spectroscopy, energy‐dispersive X‐ray spectroscopy, and scanning electron microscopy. Magnetic extraction parameters were optimized using a Doehlert matrix. Under optimum conditions, the magnetic extraction coupled with a LC–MS method shows good linearity with R2 ≥ 0.9982, suitable intra‐ and interday precision, and limits of detection and quantification in the range of 0.052–0.093 μg/L and 0.11–0.31 μg/L, respectively. Satisfactory relative recoveries of all carbamates were achieved from fortified water samples in the range of 93.89–101.01%.

“…Wastewater discharges from paper, textile, and food processing industries and pharmaceutical wastes have many adverse effects on human health and the environment. Among them, nitro compounds, especially 4‐nitrophenol (4‐NP), and organic dyes are considered toxic and harmful organic pollutants, and their removal or conversion from contaminated sites is of paramount importance 42–46 . Considering all these features, in this work, a novel magnetic nanohydrogel with Fe 3 O 4 magnetic core surrounded by a crosslinked copoly(ionic liquid) will be synthesized and then decorated by AuCo bimetallic NPs (Fe 3 O 4 @PolyIL‐AuCo).…”

Synergistic effects in bimetallic catalysts produce a catalyst with superior activity than a monometallic component. In this work, a novel magnetic crosslinked copoly(ionic liquid) nanohydrogel was synthesized and employed for the stabilization of AuCo bimetallic nanoparticles (Fe3O4@PolyIL‐AuCo). This material was characterized using different instrumental techniques such as FT‐IR, TGA, XPS, VSM, solid‐state UV–Vis, SEM mapping, and TEM. Results indicated a narrow size distribution of nanoparticles and high water dispersibility of Fe3O4@PolyIL‐AuCo. Using this catalyst, a series of nitroarenes were reduced to the corresponding amines in aqueous media. In addition, organic dyes were efficiently degraded by this catalyst. Different experiments dealing with the same transformation confirmed that Fe3O4@PolyIL‐AuCo exhibited higher catalytic activity than the similar monometallic Au and Co catalysts. This catalyst was recycled for at least 11 consecutive runs with very small deactivation, and TEM, VSM, and XPS confirmed the stability of the reused catalyst.
