Determination of fluoride ions in urinary stones by ion chromatography

Selective fluoride sensing by a novel series of lanthanide-based one-dimensional coordination polymers through intramolecular proton transfer

“…1 The beneficial domain includes dental health care, 1 g , j , k ,2 osteoporosis therapy, 3 medicinal cleaning agents, environmental pesticides, 1 c , g , h positron emission tomography, 4 and material industries. 1 a , k Obviously, all of these useful applications have an upper limit, exceeding which will lead to detrimental effects, which include osteoporosis and related diseases, 3 fluorosis, 1 g urolithiasis, 5 neurological and metabolic disorders, 1 i , k gastric and kidney malfunctions, 1 k cancer, 6 and low intelligent quotient in child. 7 Notably, due to the small size and high charge density of F − and the high polarity of water molecules, there is an easy association of F − with water molecules through strong H-bonding interactions, thereby making water the most efficient carrier for F − .…”

Determination of trace fluoride in water samples by silylation and gas chromatography/mass spectrometry analysis

“…For example, determination of the fluoride ion by the selective‐ion electrode method is easily disturbed by the coexisting ions in the solution, 10 and the potential drift of the electrode will also interfere with its determination 11 . As for ion chromatography, the retention of the fluoride ion is very weak on the anion‐exchange column, and its detection is easily interfered with by organic acids 12 . The above method is not suitable for the detection of the fluoride ion in complex matrices, such as sea water and waste water 13 …”
