Liquid-phase extraction combined with X-ray fluorescence spectrometry for the elemental determination

Multiresponsive luminescent sensing behaviour of a tetraimidazole ligand and its 3D Cd(ii) metal–organic frameworks

“…The detection of metal cations and anions in various environments is significantly important not only in agriculture, 1 industry 2 and biological processes, 3 but also in the ecosystem and public health. 4 To date, many methods for the detection of these ions have been applied in laboratories and industry, such as electrochemical detection, 5 atomic absorption spectroscopy, 6 inductively coupled plasma mass spectrometry, 7 high performance liquid chromatography, 8 neutron activation analysis, 9 X-ray fluorescence spectrometry, 10 surface plasmon resonance, 11 surface enhanced Raman scattering method, 12 absorption and fluorescence spectroscopy. 13 Among these methods, fluorescence sensing based on the changes in fluorescence intensities or emission wavelengths of sensor materials has been developed because of its good selectivity, high sensitivity, low cost, convenience and non-destructive nature towards substrates.…”
