Nanomaterials are promising candidates to overcome the water quality issues caused by dye consuming industries. However, their restricted efficiency in water treatment hinders their practical applications, particularly in the case of dispersed nanomaterials used in water systems. This study presents a novel approach for immobilizing ferromagnetic nanocomposites on a polymeric microporous structure. 100 mg L−1 Zn0.5Mn0.5Fe2O4 nanocomposites (NCPs) were embedded into poly(methyl methacrylate) (PMMA), eliminating the need to retrieve the dispersed nanomaterials after water treatment. The developed Zn0.5Mn0.5Fe2O4–PMMA nanocomposite was characterized by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. The removal of two commercial dyes (Brilliant Blue and Allura Red) at concentration levels of (0, 25, 35, 50, 70, and 100 mg L−1) was examined by batch adsorption studies followed by ultraviolet-visible (UV-vis) spectrophotometry quantification. It was observed that the maximum removal percentage was obtained for the embedded Zn0.5Mn0.5Fe2O4 nanoparticles on the PMMA polymer using 100 mg of Zn0.5Mn0.5Fe2O4 NCPs for all the four dye levels in comparison to dispersed Zn0.5Mn0.5Fe2O4 nanocomposites. It was observed that the maximum adsorption of Brilliant Blue and Allura Red was obtained under alkaline conditions, pH 7.32 and 8.37, respectively. It was suggested that Zn0.5Mn0.5Fe2O4–PMMA can be applied as a sustainable material to enhance water treatment efficiency by merging the advantages of a fast preparation technique and a higher adsorption capacity to remove complex organic contaminants.

NJC (New Journal of Chemistry) is a broad-based primary journal encompassing all branches of chemistry and its sub-disciplines. It contains full research articles, communications, perspectives and focus articles. This well-established journal, owned by the Centre National de la Recherche Scientifique (CNRS) of France, has been co-published with the Royal Society of Chemistry since January 1998. NJC is the forum for the publication of high-quality, original and significant work that opens new directions in chemistry or other scientific disciplines. In addition to having a significant chemical component, work published in NJC must demonstrate that it will have an impact on areas of research other than that of the reported work.
