| 제목 | Organophosphate-comprised porous organic polymers for effective removal of heavy rare earth elements in aqueous solutions |
| 초록 | Owing to the ever-increasing demand on the rare earth ions, their recovery from wastewater has gained considerable interest. We have developed two novel organophosphate-comprised porous organic polymers (BPOP-1 and BPOP-2) with large surface areas through a facile one pot reaction strategy. Subsequetly, the BPOPs were applied for the adsorptive separation of four heavy rare earth elements (HREEs), Eu3+, Gd3+, Tb3+, and Dy3+. Remarkably, both BPOPs showed among of the highest HREEs adsorption capacities reported.. We have proposed a palusible adsorption mechanism for HREEs capture over the BPOP adsorbent. The adsorbents showed good reusuability for 10 successive cycles without any significant deterioration in adsorption capacities.AcknowledgmentsThis work was supported by the National Research Foundation of Korea (NRF) grants funded by the Korea government (MSIT) (No. NRF‐2019R1A2C2002313 and No. 2020R1A5A101913). |
