“…It could be found that the semicircle parts of modified electrodes were smaller than that of bare SPCE, which indicated the decreases in resistance after modifications. The Rct of finally nafion/UiO-66/GN/SPCE demonstrated the most decrease, indicating that the GN and UiO-66 improved the conductivity of the sensor in the presence of nafion ( Manoj et al, 2022 ). The effective area of nafion/UiO-66/GN/SPCE could be calculated by the Randles-Sevcik equation (I p = 2.69 × 10 5 A D 1/2 n 3/2 υ 1/2 C), where A is the effective area of the electrode (cm 2 ), D is the diffusion coefficient of K 3 [Fe(CN) 6 ] (7.6 × 10 −6 cm 2 s −1 ), n is the transfer number of electrons, υ is the scan rate (V s −1 ) and C is the concentration of K 3 [Fe(CN) 6 ] (5 mmol L −1 ).…”

“…With the increasing concern of human health problems and environmental pollution, coordination polymer (CPs), as a fluorescent chemical sensing material has been widely used because of their numerous advantages, such as simple operation, fast reaction, high sensitivity and selectivity, and low detection limit. , They have been successfully used as fluorescent probes to detect explosives, ions, , temperatures, biomarkers, gas, etc. In 2022, our team reported a lanthanide fluorescence CP [Tb 2 (adip)(bdc)(NMP) 4 ] (H 2 bdc = 1,4-dicarboxybenzene) as a single-emission “turn-on” fluorescence sensor for detecting aztreonam .…”

By the solvothermal assembly of Gd(NO3)3·6H2O, H2dht (H2dht = 2,5-dihydroxyterephthalic acid), and H4adip (H4adip = 5,5′-(anthracene-9,10-diyl)diisophthalic acid), a luminescent coordination polymer (CP) [Gd(adip)1/2(dht)1/2(NMP)2] (1, NMP = N-methylpyrrolidone) has been prepared. 1 exhibits dual emission bands and has the fluorescence turn-on behavior toward pH and antibiotic amikacin (AMK). Therefore, 1 can serve as a luminescence turn-on self-calibrated sensing material to quantitatively detect pH value and AMK. In the pH range of 5.05–6.88, the sensitivity can reach 2296% per pH, which is the highest among all fluorescence pH sensors. 1 also shows excellent sensing properties for AMK, and a good linear relationship between the fluorescence intensity ratio and concentrations of AMK was observed with a slope of 1.2 × 105 M–1. The limit of detection (LOD) is 7.7 × 10–8 M. Meanwhile, 1 is also the first CP-based sensing material to detect AMK. In order to better understand the sensing phenomenon, we also discussed the sensing mechanism for pH and AMK in detail.

As the mining industry spreads to new areas in the arctic regions, the need for re-useable efficient methods for mine chemicals' recycling increases. Especially in the case of xanthates, which are used as collectors for many metals from ore. Xanthates are very toxic to aquatic life either directly or indirectly and cause potentially severe health problems to humans after long-term exposure. In the present work, potassium ethyl xanthate (KEX) was observed to coordinate into metal organic frameworks (MOFs). HKUST-1 and its post-synthetically modified forms were observed to behave most effectively of the studied MOFs at low concentrations of KEX. Differences in the uptake of KEX were detected regarding the synthesis method in the case of MIL-100(Fe) synthetized by solvothermal and mechanochemical methods. Other studied MOFs, UiO-66 and MIL-100(Al)/MIL-96(Al), were not observed to be effective in KEX uptake.
