Experimental and theoretical investigations of Cs+ adsorption on crown ethers modified magnetic adsorbent

[Display omitted] •A bifunctional absorbent for Cs+: Fe3O4@18-Crown-6 ether is developed.•The adsorbent has a superparamagnetic property, allowing an easy recycling.•The adsorbent has a high capacity and high selectivity of Cs+ adsorption.•The experimental results are supported by the DFT calculatio...
