To solve water pollution caused by oil spillage, a new sorbent was prepared by radiation-induced graft polymerization. Acrylate monomer was introduced to polypropylene nonwoven and hydrophobic groups were introduced by the grafting method. The grafting degree of sorbent was determined as a function of monomer concentration and solvent solubility for monomer. Fourier transform‐infrared spectra and static contact angle measurements were used to characterize the chemical changes of the polypropylene nonwoven surface. The grafted sorbent showed a fast sorption rate and a maximum sorption capacity of 13.56 g/g for diesel oil, while the original polypropylene nonwoven was only 7.48 g/g. In addition, retention measurement and the reusability test were conducted to evaluate the suitability of the polypropylene‐acrylate grafted nonwoven for the treatment of oil spillage.
