In this study, some synthetic methods of condensation, substitution, and amidoxime reaction were used to prepare a kind of new fungal-modified material containing the monoamidoxime terminal open-chain polyether, and its microstructure and morphology were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, Brunauer–Emmett–Teller analysis, and thermogravimetric analysis. The single-factor method was used to preliminarily investigate uranium­(VI) adsorption capacity of the target material influenced by some factors. On this basis, then the orthogonal experiment was applied to further obtain the optimal adsorption conditions (initial U­(VI) concentration: 40 mg L–1, solid–liquid ratio: 25 mg L–1, initial pH value: 6.0, and contact time: 130 min) and the maximum adsorption capacity (295.48 mg g–1). The cyclic adsorption–desorption and anti-interference experiments showed that the target material had good regeneration and uranyl selectivity adsorption performance. Langmuir (nonlinear) (R2 = 0.9704) and Freundlich (nonlinear) (R2 = 0.9675) isotherm models and a pseudosecond-order kinetic model (linear) (R2 = 0.9922) were closely fitted with experimental data, and the uranyl-loaded mechanism should be mainly the monolayer and chemical adsorption process.
