Sodium alginate is a polysaccharide compound extracted from natural plants that has been successfully prepared as hydrogel for adsorbing and removing pollutants. However, the selectivity of alginate-based hydrogels to malachite green (MG) dyes stability in air cannot meet requirements. Herein, metal–organic frameworks (MOFs) are embedded into magnetic create MOF (MMOF hydrogel) microspheres with high adsorption capacity. The morphology physical properties MMOF were characterized by scanning electron microscopy optical microscopy. Under optimized conditions, rate MG reached 96.5%. maximum capacity was determined be 315 mg·g−1. This highly efficient adsorbent dye removal considerable potential rapidly toxic contaminants aquatic food matrices high-throughput sampling pretreatment, which rapid, green, large-scale environmental remediation future.

Abstract In this study, graphene oxide (GO) nanosheets were chemically modified by attaching polyaniline (PAN) nanoparticles to their surfaces, creating a partially reduced composite (PAN@PRGO). This synthesized PAN@PRGO nanocomposite serves as an innovative and highly effective adsorbent for removing indigo carmine (IC) dye from water. The morphology chemical composition of analyzed using various techniques, including scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), photoelectron (XPS), confirming the successful grafting PAN onto GO surface. Batch adsorption tests showed that has outstanding capacity dye, achieving 490.0 mg g −1 at pH 5.0 298 K. is notably higher than alone (317.25 ) exceeds other materials reported in literature. Additionally, demonstrated 100% removal efficiency IC concentrations up 300 L . experimental data closely matched Langmuir isotherm model pseudo-second-order kinetic model, suggesting electron-sharing interactions between contribute mechanism. adsorbed was recoverable 0.1 M NaOH solution, with retaining near-100% even after five adsorption–desorption cycles. These results indicate promising, reusable industrial wastewater.
