A nanocomposite composed of rGO and γ-Fe2O3 was prepared using ultrasonication for the adsorption malachite green (MG) dye. The preferential plane diffractions at 2θ values 35.54° 26.45° about (311) (002) with 19.85 20.92 nm crystallite sizes, respectively confirmed successful formation nature adsorbent. Moreover, XPS FTIR results also composite due to existence peaks relevant composite's components. adsorbent's surface charge (pHPZC = ~ 7.1) estimated salt addition technique. To minimize experiments optimize parameters removal MG by 25 °C, central design (CCD) response methodology (RSM) used. optimal obtained from within-range numerical optimization based on 0.923 Derringer's desirability function were 200 mg/100 mL dose, 80 ppm dye solution, 7.99 pH 112.68 min. contact time 90% 40.64 mg/g capacity (qm) rGO/γ-Fe2O3. However, 98% 64.26 achieved upon extended-range estimation parameters. data exhibited best co-relationship Freundlich isotherm pseudo-2nd order kinetic model. According a thermodynamic analysis, process rGO/γ-Fe2O3 is exothermic, spontaneous, less random. thermal stability, desorption, regeneration reusability explored. Finally, this study shows that RSM can be an excellent technique industrial scale.

Metal–Organic Framework (MOF)-Embedded Magnetic Polysaccharide Hydrogel Beads as Efficient Adsorbents for Malachite Green Removal

Molecules, Год журнала: 2025, Номер 30(7), С. 1560 - 1560

Опубликована: Март 31, 2025

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.
