“…The same Chinese research group 381 demonstrated precise and accurate measurements of 143 Nd/ 144 Nd without separating Nd from Sm. Instrumental mass discrimination was corrected using 146 Nd/ 144 Nd as an internal standard, after correction of the isobaric interference of 144 Sm on 144 Nd using interference-free 147 Sm/ 149 Sm for mass fractionation. Their data indicated that the mass discrimination of Sm and Nd was not the same and varied during an analytical session, hence the need to calculate mass biases for each element on individual samples.…”

This study is related to the determination of fluoride ion by the conversion of pink-colored Fe(III) and indole-3-acetic acid (IAA) into a colorless hexafluoride ferrite complex with the addition of fluoride. The optimum conditions of the complex formation were found to be pH 1.7 and a temperature of 60°C. The maximum absorption wavelength of the complex and the detection limit of the method were 525 nm and 0.26 mg/L, respectively. The interfering effects of the different cations (Ag + , Al 3+ , Ba 2+ , Ca 2+ , Cd 2+ , Co 2+ , Cu 2+ , K + , Mg 2+ , Na + , Ni 2+ , Pb 2+ ) and anionswere also investigated. The method was applied to standard and real samples and the resulting data were statistically compared at a confidence level of 95% with those obtained with the use of a fluoride-selective electrode.

“…The spectroscopic techniques viz proton nuclear magnetic resonance ( 1 H NMR), time‐resolved absorption spectra and time‐resolved fluorescence spectra etc. utilized to explore the cyanide binding and its sensing process offer only the indirect information regarding photophysical properties and geometries . The density functional theory and time‐dependent density functional theory (DFT/TDDFT) methods are being used to study the cyanide binding, ICT and other mechanisms of cyanide fluorescent chemosensing .…”

The synthesis of fluorescent chemosensors has remained a focus for most of the studies, but detailed mechanisms of sensing are still lacking. Density functional theory (DFT) and time dependent-density functional theory (TD-DFT) methods have been utilized to investigate the cyanide anion sensing mechanism of 3,5-diformyl-borondipyrromethene (1). The natural charges on carbons of the formyl groups of 1 indicate that these carbons are prone to nucleophilic addition. The analysis of the frontier molecular orbitals designates the first excited state (S 1 ) of 1 as a local excited state with p ! s* transition. Likewise, S 1 of 2 (the cyano form of 1) is a charge separated state, showing intramolecular charge transfer (ICT) which is responsible for inducing the fluorescence quenching in 2.[a] Dr.
