“…8 In fact, the molecule presents two main absorption peaks at 259 and 278 nm. 47 Aware of such limitations, we first evaluated visible Raman LOD by performing a high concentration series (from 500 mg/l to 10 g/l (Fig. S7, Supplemental Material).…”

Short-wavelength (λ < 260 nm) Raman spectroscopy offers an advantage of a generally higher sensitivity than Raman spectroscopy in the visible range. An application with high potential is its use for environmental water analysis targeting archetypal compounds that are present in industrial and urban sewage water. However, this application is feasible only if specific performance benchmarks are met. We validate the applicability of a simple and cost-effective deep-UV Raman spectrometer (λ exc = 236.5 nm). The analysis brings to the fore that the experimentally derived detection limits the studied archetypal compounds are to high by several orders of magnitude. We outline potential further development and associated limitations. These are the deterioration of the analysed species by photolysis as a consequence of the high photon energy and intensity, and the self absorption of the UV radiation. These effects are explained and partially corrected along a simple mathematical model from which a general limit of detection is estimated.

“…Nowadays, the analysis methods which are commonly used in the detection of trace BTA in water mainly include high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-HESI-MS/MS), high-performance liquid chromatography-diode array detection (HPLC-DAD), gas chromatography–mass spectrometry (GC-MS), liquid chromatography–mass spectrometry (LC-MS), and fluorescence spectrometry. − Although trace BTA can be very sensitively detected using the aforementioned methods, they are unsuitable when a rapid and real-time detection of BTA is required due to their shortcomings, such as complicated pretreatments, expensive and nonportable instruments, laborious operations, high usage costs, and long analysis times. As a result, it is urgently needed to develop a sensing platform with high sensitivity that can be operated simply to detect trace BTA in water swiftly.…”

Benzotriazole in trap water is a potentially danger for human health, and its rapid and real-time monitoring is thus very desirable. Here, a flexible SERS sensing platform was fabricated on Ti plate utilizing poly diallyldimethylammonium chloride, Ag nanoparticles, Ti3C2 nanosheets, and poly(vinyl alcohol). Next, the SERS effect for benzotriazole in water was systematically explored. Our investigation shows that this SERS sensing platform is extremely sensitive to benzotriazole in water. The limit of detection (LOD) is as low as 0.01 nmol L–1. Besides, it also possesses excellent repeatability (point-to-point RSD 6.8%) and reproducibility (batch-to-batch RSD 6.2%), strong antijamming performance, good flexibility, and outstanding mechanical stability and can respond rapidly to trace benzotriazole in water. More intriguingly, this SERS sensing platform can reveal high sensitivity for trace benzotriazole in tap water, with a minimal detection limit of 0.1 nmol L–1. Sensitive qualitative analysis as well as quantitative detection can be achieved in the range of 10–4–10–10 mol L–1, demonstrating that it may be a powerful tool in the online monitoring of trace benzotriazole in tap water. Taken together, our investigation might open up an avenue in designing MXene-based SERS substrates for real-time detecting trace benzotriazole in tap water.

“…Fluorescence spectroscopy is a useful analytical tool for both laboratory analysis and in situ field sampling. [1][2][3][4][5][6][7][8][9][10][11][12] When the fluorescence of the analyte dominates a region of the optical spectrum, a simple filter fluorometer may be a suitable tool to make quantitative measurements of the analyte following calibration.…”

We recently described a lightweight, low-power, waterproof filter fluorometer using a 180° backscatter geometry for chlorophyll-a (chl- a) detection. Before it was constructed it was modeled to ensure it would have satisfactory performance. This manuscript repeats the modeling process that allows the calibration slope and detection limit for a fluorescent analyte in water to be estimated from system component performance and conventional spectrofluorometry alone. These values are validated by comparison to the experimental result of calibration from the completed instrument. Our model yields a calibration slope of 8.22 mV-L/µg for dissolved chl- a, consistent with the experimentally measured slope of 8.21 mV-L/µg. The detection limit modeled from this slope and an estimate of the baseline noise of the instrument was 0.15 µg/L chl- a, while the measured detection limit using real blank samples was 0.18 µg/L, in 0.1 s differential measurements.
