An Anionic Metal-organic Framework for Selective Adsorption Separation toward Methylene Blue and Rhodamine B

Microporous metal organic framework NOTT-210 was synthesized via solvothermal and dyes adsorption and separation properties were determined and discussed. NOTT-210 with anion characteristic can selective adsorb low concentrations of cationic dyes from effluents at room temperature. And that NOTT-210 can also separate the MB+(methylene blue) and RB+(rhodamine B) molecules because of size-dependent effect and kinetics-dependent effect. Hence, NOTT-210 is among the very few porous MOFs which not only can adsorb low concentrations of MB(+)and RB(+)molecules but also has the ability to separate their mixture.
