Rapid Analysis of Polycyclic Aromatic Hydrocarbons in Water Samples Using an Automated On-line Two-Dimensional Liquid Chromatography

Development and Optimization of an External-Membrane Introduction Photoionization Mass Spectrometer for the Fast Analysis of (Polycyclic)Aromatic Compounds in Environmental and Process Waters

“…Fast and sensitive analysis of aromatic hydrocarbons (AHs) and polycyclic aromatic hydrocarbons (PAHs) in aqueous matrices is vitally important, because of their high impact on environmental and human health. , The low concentrations of AHs and PAHs in environmental bodies of water complicate their monitoring . Although available chromatographic offline techniques offer clear advantages, with respect to sensitivity, − various laborious enrichment techniques (e.g., purge-and-trap, solid-phase extraction, liquid–liquid extraction) must be applied to increase the concentrations to a detectable level. − For this reason, the development of online techniques moves into focus. A simplified analytical method for PAHs and similar compounds in complex matrices has been developed by Mirabelli et al by using online solid-phase microextraction (SPME) coupled to atmospheric-pressure photoionization mass spectrometry (APPI-MS).…”

Quantification Strategies for Two-Dimensional Liquid Chromatography Datasets Using Regions of Interest and Multivariate Curve Resolution Approaches

“…The ROIMCR procedure has also been validated for qualitative analysis and relative quantification of LC×LC-MS datasets, in metabolomics and pharmaceutical analyses [26,27]. In addition, there are still many other fields to be explored, such as foodomics [3,4] or environmental analysis [5,6].…”

“…The use of comprehensive two-dimensional liquid chromatography (LC×LC) has considerably grown in the last decade [1]. Instrumental developments (for instance, modulation interfaces [2]) have facilitated the implementation of multidimensional liquid chromatography in various research fields, such as food [3,4], environmental [5,6], traditional Chinese medicine [7], pharmaceutical [8,9], proteomic [10,11], or metabolomic [12,13] analysis, among many others. However, regardless of the latest improvements in LC×LC, data analysis remains a major bottleneck due to the high complexity and huge size of the generated datasets.…”

Endosulfan Elimination Using Amine-Modified Magnetic Diatomite as an Adsorbent

“…Pesticide removal techniques such as ozonation, hydrostatic pressure, and adsorption approaches have been widely employed (Chen et al, 2013a;Iizuka et al, 2013;Rasolonjatovo et al, 2017). Additionally, various adsorbents such as cryogels, monoliths, particles (magnetic, non-magnetic) and membranes (for filtration) have been used as an effective alternative adsorbents for the removal of organic pollutants from aqueous medium (Çorman et al, 2017;Acet et al, 2018;Armutcu et al, 2019). Furthermore, agricultural wastes such as silica and clay minerals (e.g., montmorillonite, zeolite, bentonite and kaolinite) have been employed as a cost-effective adsorbent to remove pesticides (Gimsing et al, 2007;Donia et al, 2012;Arnnok and Burakham, 2014).…”
