Abstract:A novel 3D europium-based cationic framework (Eu-CMOF) has been constructed solvothermally by employing a viologen derivative as an organic functional building unit. Notably, Eu-CMOF demonstrates its capability as a proficient aqueous-phase ion-exchange host, facilitating the remarkable rapid chromatographic column separation of new coccine and malachite green (NC 3− /MG + ), as well as new coccine and methylene blue (NC 3− /MLB + ), in mere 2 to 4 min. Adsorption thermodynamics and kinetics of anionic dyes de… Show more
