Facile preparation of covalent organic frameworks@alginate composite beads for enhanced uranium(Ⅵ)adsorption
文献摘要:
Covalent organic frameworks(COFs)have broad application prospects in adsorption and separation.Yet,as COFs are generally in powder form,their superior performance at the laboratory scale is difficult to transfer into pilot-or industrial-scale use.Thus,there is a strong and urgent need to structure COFs into monolithic mate-rials.Herein,a facile strategy was developed to prepare COFs@alginate composite beads.Three composite beads comprising different COFs including TpPa-1(2,4,6-tri-formylphloroglucinol(Tp)and p-phenylenediamine(Pa-1)as monomers),TpDb(Tp and 2,5-diaminobenzonitrile(Db)as monomers)and TpTt(Tp and 1,3,5-triazine-2,4,6-tri-amine(Tt)as monomers)with controlled COF loading and product size have been facilely achieved via this strategy,validating the applicability of this method.Furthermore,the representative TpDb@alginate composite beads showed good adsorption performance of uranium(Ⅵ)in aqueous solution with high adsorption capacity(635 mg·g-1),good interference immunity and recycla-bility.This work offers a practical approach for incorpo-ration of COFs into polymer matrix,which can serve as potential adsorbents for radioactive wastewater treatment.
