Magnetic-field-free separation and recovery of MXene-doped GO composites via dye-bridged reassembly in dye adsorption
Abstract
. The MB removal capacity of the composite was maintained over a wide pH range, with dye-bridged reassembly preferentially occurring under acidic and weakly alkaline conditions (pH 3-9). Higher dosages enhanced MB removal but impaired the dye-bridged reassembly, whereas thermal annealing reduced the composite adsorption capacity but preserved its dye-bridged reassembly ability. Although the presence of cations hindered MB adsorption, they promoted reassembly efficiency, which was positively correlated with cation valence. A quantitative recovery of approximately 95% was achieved with the GO/MXene composite. The proposed strategy enables efficient and scalable dye removal and offers a new path for high-performance and sustainable dye wastewater treatment.
