Abstract: In this study, a novel crown-ether-functionalized nano magnetic solid-phase extractant (CFE) for extracting Rb+ was successfully prepared by the following three steps. First, the magnetic core of Fe3O4 nanoparticles was synthesized by a solvothermal method. Second, the SiO2-NH2 group was coated on the surface of the magnetic core to prepare an intermediate product of Fe3O4@SiO2-NH2 by ester hydrolytic reaction of (3-aminopropyl)triethoxysilane in an alkaline environment. Third, the targeted functional group of crown ether was then modified on the surface of the intermediate product to prepare a novel CFE extractant by an amidation reaction between the carboxyl group in 4′-carboxybenzo-18-crown 6-ether and the amino group on Fe3O4@SiO2-NH2 under the catalysis of N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride. Then, the characteristics of micro morphology, magnetization, X-ray diffraction, infrared absorption, and elemental composition of the Fe3O4, Fe3O4@SiO2-NH2 and CFE were analyzed, which had lent support to the successful preparation of these materials. The extraction ability for Rb+ of this novel CFE material was verified. Moreover, the effect of solution pH on Rb+ extraction rate was explored, and the results showed that CFE had a best extraction rate of 90.0% for Rb+ at the pH 13 (at room temperature, extracting for 30 minutes).
