Dispersity of metal ions in MOF-808-EDTA. STEM-HAADF images (scale bar, 100 nm) and the corresponding elemental maps for a MOF-808-EDTA, b–d single-metal systems (MOF-808-EDTA with loaded La3+, Hg2+, and Pb2+, respectively), e binary system (MOF-808-EDTA with loaded Co2+ and Ni2+), and f ternary system (MOF-808-EDTA with loaded Cu2+, Rh3+and Ru3+)
