“…5 Hence, effective measures for reducing and controlling the release of MG are urgently needed to protect water resources, ecosystems, and human health. Various methods have been utilized to mitigate the presence of MG in polluted water, including membrane separation, 6 photocatalytic 7 and biological 8 degradation, as well as adsorption. 9 Among these methods, adsorption has emerged as a widely applied method in water treatment due to its simplicity, efficiency, economic viability, and recyclability.…”

In this study, dopamine-modified graphene aerogel (DGA) is synthesized through a one-step hydrothermal method using graphene oxide as the precursor and dopamine as the reducing agent. Subsequently, in situ immersion synthesis is conducted to obtain ZIF-8 loaded on a dopamine-modified graphene aerogel skeleton (ZDGA), featuring a regular honeycomb interconnected mesoporosity and a high specific surface area of 532.8 m2/g. The synthesized ZDGA exhibited exceptional adsorption performance for the cationic dye malachite green. At room temperature, ZDGA achieved an impressive equilibrium adsorption capacity of 6578.34 mg/g. The adsorption process followed pseudo-secondary kinetics and adhered to the Langmuir model, indicating chemically dominated adsorption on a monomolecular layer. Intraparticle diffusion was the primary rate determinant, with π–π stacking, electrostatic adsorption, hydrogen bonding, and Lewis acid–base interactions serving as the key driving forces. It has an ideal specific surface area and good cycling performance, which highlights its potential application in dye wastewater treatment.
