A coumarin-based colorimetric receptor coupled with a smartphone for the determination of fluoride concentration in drinking water
{{output}}
The excess residues of fluoride ions (F-) in drinking water cause serious human health problems, making their detection and measurement highly essential. In this work, a coumarin-based receptor (4-methyl-1-(1-(6-nitro-2-oxo-2H-chromen-3-yl)ethylidene)thiosemic... ...
