“…[8,9] Therefore, how to deal with Th (IV) contaminated solution effectively and reasonably is of great significance to the sustainable development of nuclear energy, ecological environment protection and human health. [10,11] All thorium in nature is 232 Th, mainly in the form of + 4 valence, and the form of Th (IV) is easily affected by pH in aqueous solutions. When pH < 2, the form of thorium is mainly Th 4 + , and when pH > 3, it undergoes intense hydrolysis to form coordination ions.…”

Bis (diphenyl phosphate) imine (Htpop) was synthesized using a simple one‐step solvent method to remove thorium (IV) from aqueous solutions. The structure, functional group displacement, morphological differences, and elemental composition of the samples were analyzed using characterization techniques such as NMR, FTIR, SEM, EDS, and XPS. According to the batch experiment, when pH=4.0 and temperature was 298 K, the adsorption equilibrium can be reached within 40 min, and the adsorption capacity was 189.32 mg ⋅ g−1. The adsorption process conforms to the quasi‐second‐order kinetic model (R2=0.9959) and Langmuir model (R2=0.9971). Thermodynamic data (▵H0<0, ▵G0<0) indicate that the adsorption behavior of thorium (IV) in Htpop was spontaneous and exothermic.
