英文摘要Hypercrosslinked polymers (HCPs) with synergistic effect of ether oxygen and phenolic hydroxyl groups was designed and fabricated for Cs+ isolation in the salt lake system. The separation factors (S.F.)(Cs+/K+) of the adsorbents were significantly increased through regulating the content of the ether oxygen group in the frameworks. The S.F. of PO-HCPs-6 was increased by nearly 5 times to an ultra-high value (S.F. = 57) compared with the Cs+ adsorbents reported in the literature. Moreover, the mild and sufficient polymerization process endowed PO-HCPs-6 with an extremely fast kinetic adsorption rate. PO-HCPs-6 could quickly reach 90% of the equilibrium adsorption capacity in just 1 min. Finally, after 5 times adsorption-desorption experiments, the remarkable elution rate (> 92%) and reusability adsorption capacity (> 91%) of PO-HCPs-6 proved it has inspiring application potential for the Cs+ isolation in the salt lake brine system.
