The goal of this study is to enhance the loading amount of crown ethers so as to improve the adsorption capacity for cesium (Cs<sup>+</sup>) from salt lakes. Results showed that the nanofiber membrane with a fiber diameter of 310–340 nm was obtained by precisely controlling the viscosity of the spinning system (650–700 mPa·s) and the grafting reaction time (10 h). The grafting degree of crown ether was enhanced from 17.3 % (18C6PI) to 84.8 % after DAB18C6 grafting. Dynamic cyclic adsorption experiments revealed that the 18C6-g-18C6PI nanofiber membrane achieved a Cs<sup>+</sup> adsorption capacity of 85.23 mg g<sup>−1</sup>, which is significantly higher than that of the 18C6PI nanofiber membrane (68.21 mg g<sup>−1</sup>).
