“…Absorbing solutions composed of substances such as NH 3 , NaOH, or buffer solution (Na 2 CO 3 /NaHCO 3 ) are commonly used. 25,28,30,31 Thus, the influence of different absorbing solutions (50 mmol L -1 NH 3 , 100 mmol L -1 NH 3 , H 2 O, 3.2 mmol L -1 Na 2 CO 3 + 1.0 mmol L -1 NaHCO 3 and 32 mmol L -1 Na 2 CO 3 + 10 mmol L -1 NaHCO 3 ) containing 150 mmol L -1 of H 2 O 2 on the concentration of Cl, F and S in drill cuttings were evaluated and the results are shown in Figure 4.…”

The assessment of chlorine, fluorine, and sulfur concentrations in depth profile of drill cuttings was performed using ion chromatography after sample preparation by pyrohydrolysis. The parameters for pyrohydrolysis were optimized using a Box-Behnken design, and the established conditions were 300 mg of sample, 300 mg of V2O5, temperature of 1000 °C, reaction time of 25 min, and absorbing solution of 50 mmol L-1 NH3 + 150 mmol L-1 H2O2. The accuracy was evaluated by the analysis of certified reference materials and recovery tests, and the results showed a good agreement between determined and certified values and recoveries (89-108%). The precision (relative standard deviation (RSD) < 10%), and the limits of detection (0.5-2.5 mg kg‑1) were suitable for drill cuttings analysis. The concentration of chlorine, fluorine, and sulfur in drill cuttings at different depths was at mg g-1 range, and its variation is related to the mineral composition of the samples.

“…Dysfunction of intracellular Cl – homeostasis has been found to be closely linked with several human diseases such as cystic fibrosis, epilepsy, and chronic pain. − Therefore, monitoring and quantifying Cl – concentration in situ at a cellular level play a key role in understanding intracellular regulation of Cl – and its linkage with diseases. Various approaches have been developed for quantifying Cl – concentration including ion chromatography, spectrophotometry, colorimetry, and photodynamic ion coextraction . These methods are accurate and good for offline and ex situ measurements , but are not applicable for intracellular Cl – quantification.…”

Long-Term Quantitatively Imaging Intracellular Chloride Concentration Using a Core-/Shell-Structured Nanosensor and Time-Domain Dual-Lifetime Referencing Method

et al. 2020

Luminescence lifetime-based nanosensors for chloride ions were designed by incorporating a luminescent ruthenium dye [Ru(1,10-phenanthroline)3] inside silica nanoparticles and chemically labelling their outer surface with chloride ion-sensitive fluorescent dyes (N,N′-bis(carboxypropyl)-9,9′-biacridine). The nanosensor surface was further functionalized with positively charged amino groups to facilitate intracellular uptake via endocytosis and target lysosomes. The nanosensors have an average diameter of 52 nm and are monodispersed in aqueous solutions. Because of the long lifetime of the reference ruthenium dye, the sensor response can be analyzed using the time-domain dual-lifetime referencing (td-DLR) approach. The use of pulsed excitation in td-DLR rather than intense continuous illumination in ratiometric measurements greatly prevents the dye from photobleaching which significantly improves its measurement stability and reproducibility for long-term monitoring. At optimum conditions, the sensor can measure chloride concentration in the range of 0–200 mM with a large ratiometric signal change from 140.9 to 40.2. Combined with our custom-built microscopic td-DLR system, variations of intracellular chloride concentration in lysosomes were imaged quantitatively with a high spatial resolution and accuracy.

Boron is an element with a wide range of uses. Boron, which is the main component in boron minerals, is present as a minor component or even a trace component in other sources. Depending on the increase in the boron usage areas, the boron concentrations in environmental samples such as water, soil and air is also increasing. Therefore, it is important to determine boron in such samples accurately and precisely. In order to determine boron in various sample matrices, various analytical methods have been developed and used. This review focuses on the analytical methods for the determination of boron in various sample matrices. This review covers approximately the last four years (2015-August 2018), offering a critical review of the boron determination by various techniques.
