“…Therefore, there is a strong demand for simple, rapid and sensitive methods that allow evaluating and monitoring PAH in environmental water samples at trace level. For such purpose, different analytical techniques have been employed like gas chromatography coupled with time-of-flight mass spectrometry (GC-TOF-MS) [7], flow injection capillary electrophoresis [8], high-performance liquid chromatography (HPLC) with UV-vis and fluorescence detection [9]. GC-TOF-MS is one of the best methods for direct determination although it is not cost-effective; further, these compounds are difficult to ionize.…”

Quenching of fluorene fluorescence by single-walled carbon nanotube dispersions with surfactants: application for fluorene quantification in wastewater

The fluorescence of fluorene in aqueous solutions of surfactants of different natures, anionic sodium dodecylsulphate (SDS), cationic cetyltrimethyl ammonium chloride (CTAC) and non-ionic polyoxyethylene-23-lauryl ether (Brij 35), as well as in single-walled carbon nanotube (SWCNT) dispersions in these surfactants, has been studied and compared. A fluorescence quenching phenomenon has been observed in the presence of SWCNT, the effect being stronger for dispersions in CTAC, related to the improved dispersion capability of this surfactant as revealed by microscopic observations and its stronger adsorption onto the SWCNT surfaces as inferred from the Raman spectra. SWCNT interact with fluorene causing a fluorescence quenching. The fluorescence intensity ratio, calculated in the absence and in the presence of SWCNT, follows the SternVolmer equation. For the CTAC concentration that provides the highest quenching effect, the analytical characteristics of the fluorimetric method like sensitivity, detection and quantification limits, repeatability, reproducibility and robustness have been calculated. Results demonstrate that it is possible to determine fluorene in a fortified wastewater sample in aqueous solutions of CTAC and SWCNT/CTAC dispersions, showing recoveries close to 100 %. The quenching effect found in this work could be useful for the development of an optical device that uses SWCNT-based receptors for fluorene detection and quantification in aqueous surfactant solutions.

“…HPCE enjoys some advantages in comparison to HPLC, such as shorter analysis time, less sample and solvent consumption as described above; furthermore, it is more appropriate for separating ‘dirty’ samples simultaneously and lower operating cost. However, the overall sensitivity of HPCE is about two orders of magnitude lower than that of HPLC, particularly when dealing with spectroscopic detection means, such as UV–vis spectroscopy and fluorescence (Liu et al. , 2007b; Feng et al.…”

“…Differing from GC‐MS, LC analysis obviates the thermolysis of chemical compositions and the restriction of samples volatility and stability; thus, it should be of powerful separation and high sensitivity. But there is limited analytical information one can obtain by LC analysis; moreover, LC analysis is time‐consuming and interfered by sample matrix (Liu et al. , 2007b).…”

In the recent years, a wide range of metabonomic analytical techniques are widely used in the modern research of traditional Chinese medicine (TCM). At the same time, the international community has attached increasing importance to TCM toxicity problems. Thus, many studies have been implemented to investigate the toxicity mechanisms of TCM. Among these studies, many metabonomic-based methods have been implemented to facilitate TCM toxicity investigation. At present, the most prevailing methods for TCM toxicity research are mainly single analysis techniques using only one analytical means. These techniques include nuclear magnetic resonance (NMR), gas chromatography-mass spectrometry (GC-MS), and liquid chromatography-mass spectrometry (LC-MS), etc.; with these techniques, some favourable outcomes have been gained in the toxic reaction studies of TCM, such as the action target organs assay, the establishment of action pattern, the elucidation of action mechanism and the exploration of action material foundation. However, every analytical technique has its advantages and drawbacks, no existing analytical technique can be versatile. Multi-analysed techniques can partially overcome the shortcomings of single-analysed techniques. Combination of GC-MS and LC-MS metabolic profiling approaches has unravelled the pathological outcomes of aristolochic acid-induced nephrotoxicity, which can not be achieved by single-analysed techniques. It is believed that with the further development of metabonomic analytical techniques, especially multi-analysed techniques, metabonomics will greatly promote TCM toxicity research and be beneficial to the modernization of TCM in terms of extending the application of modern means in the TCM safety assessment, assisting the formulation of TCM safety norms and establishing the international standards indicators.
