| 520 | _ | _ | |a The recent trend in the agricultural field mainly focuses on the production of products with good yield by usingpotent and highly poisonous pesticides without considering their severe hazardous side effects. These materialsare present in the soil, water, and air in trace amounts. Therefore, continuous monitoring of organophosphate(OPs) pesticides is essential from a human health perspective because of their unregulated use. In this study, wedescribe fluorescence enhancement sensing for the selective quantification of OPs in aqueous media. For this,single crystals of oxydiacetic acid functionalized barium metal; [Ba(C$_4$H$_4$O$_5$)(H$_2$O)]n was developed through geldiffusion technique at room temperature. The crystals grown were found to be an effective turn-on luminescentprobe in an aqueous medium for the sensing of malathion; one of the widely used pesticide in the agriculturefield. The techniques such as Single Crystal X-ray diffraction, FT-IR, UV-Visible Spectroscopy, TG/DTG, photoluminescentspectroscopy, etc. were used for the characterization of these crystals. The sensing experimentsclearly showed that the synthesized material suspended in water can sense malathion in aqueous media with adetection limit of 10.6676 μM/L. From the Benesi-Hildebrand plot, it is clear that there exists a binding interactionbetween the sensor and the pesticide which is in 1:1 stoichiometry. The PXRD pattern clearly suggests thatthe material is intact and there is no change in its peak position, as well as no new peaks, has emerged after thesensing experiments. The FT-IR spectra taken after the sensing experiments show peak broadening and peak shiftthereby indicating the evidence of hydrogen bonding interactions between electron-withdrawing groups of OPsand electron-rich open metal sites or organic ligand molecules of MOFs. Interestingly, the material retained itssensing ability even after the third cycle of sensing experiments. |
