Abstract
(EN)
An embodiment provides a method for measuring an ion component of an aqueous sample using a photoreactive species, including: generating a metal organic framework by combining, in a reactive solution, at least one organic linker and at least one metal; impregnating the metal organic framework with the photoreactive species; introducing the impregnated metal organic framework into an aqueous sample; and measuring an analyte component concentration of the aqueous sample, wherein the measuring comprises measuring a change in the aqueous sample, wherein the change is responsive to the analyte component dissolving at least one of: the at least one organic linker and the at least one metal, and releasing the photoreactive species. Other embodiments are described and claimed.

Selon un mode de réalisation, cette invention concerne concerne un procédé de mesure d'un constituant ionique d'un échantillon aqueux à l'aide d'une espèce photo-réactive, comprenant les étapes consistant à : générer une structure organométallique en combinant, dans une solution réactive, au moins un coupleur organique et au moins un métal; imprégner la structure organométallique avec l'espèce photo-réactive; introduire la structure organométallique imprégnée dans un échantillon aqueux; et mesurer une concentration en constituant d'analyte de l'échantillon aqueux, la mesure comprenant la mesure d'un changement dans l'échantillon aqueux, le changement étant sensible à la dissolution du constituant d'analyte dans au moins l'un parmi le(s) coupleur(s) organique(s) et le(s) métal/métaux, et libérer l'espèce photo-réactive. L'invention concerne également d'autres modes de réalisation.
