Lanthanide metal–organic frameworks as selective microporous materials for adsorption of heavy metal ions

Four microporous lanthanide metal–organic frameworks (MOFs), namely Ln(BTC)(H₂O)(DMF)_1.1(Ln = Tb, Dy, Er and Yb, DMF = dimethylformamide, H₃BTC = benzene-1,3,5-tricarboxylic acid), have been used for selective adsorption of Pb(ii) and Cu(ii).
