“…In these optimal conditions, the method was applied to the determination of Arochlors in spiked soil extracts. Moreover, Santana Rodriguez et al [81] studied dibenzofuran and PCDFs by SS-RTP on filter paper treated with NaLS, selecting thallium nitrate as heavy atom salt. The authors optimized various experimental conditions, such as the type of filter paper, irradiation time, and heavy atom salt and surfactant concentrations, and obtained rather low absolute LOD values, ranging from 4.6 ng for dibenzofuran to 34 ng for 2,4,6-trichlorodibenzofuran.…”

The analytical performances and applications of various luminescence spectrometric methods to the study and determination of pollutants present at low levels in the environment are reviewed for the last two decades (1990 – 2010). The first part concerns luminescence stationary systems, including fluorescence, photochemically-induced fluorescence, phosphorescence and related luminescence methods. In the second part, the combination of these luminescence methods with flow techniques such as high performance liquid chromatography (HPLC), capillary electrophoresis (CE) and flow injection analysis (FIA) for the detection and determination of environmental pollutants is investigated. A part of the review is also devoted to the usefulness of organized supramolecular systems, such as micellar media, cyclodextrins and calixarenes, for improving the efficiency of luminescence methods.

“…The presence of TlNO3 on the paper substrate caused a slight increase in RTP emission. Santana and co-workers (19) extended RTP studies to other PClDBFs and phosphorescence enhancers. The enhancing efficiency of TlNO3, NaI, CsI, Pb-(NO3)2, and AgNO3 was investigated for DBF, 4-ClDBF, 2,8-diClDBF, 2,4,6-triClDBF, 2,3,7,8-tetraClDBF, and 2,3,4,7,8-pentaClDBF.…”

Solid-phase extraction room-temperature phosphorimetry is evaluated for screening polychlorinated dibenzofurans in water samples. The organic pollutants are extracted from water samples on octadecyl bonded silica membranes. Water extraction is rapidly performed on a 13 mm disk by using a 100 mL syringe and a stainless steel filter holder. Room-temperature phosphorimetry is directly performed on the extraction membrane, which results in analysis times of approximately 10 min per sample. Limits of detection at the sub-parts-per-billion (ng‚mL -1 ) are obtained with 100 mL of water sample. The selectivity of the technique is appropriate for total polychlorinated dibenzofurans analysis in the presence of concomitants such as pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, and polychlorinated dibenzo-p-dioxins. At the present stage, this methodology can obviate costly chromatographic analysis of uncontaminated water samples. Since it is a nondestructive technique, it could be used in tandem with chromatographic analysis for specific compound identification of positive samples.

Environmental analysis based on luminescence in organized supramolecular systems

2006

View full text Add to dashboard Cite

The use of organized supramolecular systems-including micellar media and cyclodextrin inclusion complexes-combined with luminescence techniques in the study and determination of compounds and elements of environmental interest from 1990 to 2005 is reviewed. Analyses of environmental samples performed using fluorescence, photochemically induced fluorescence and phosphorescence spectroscopy as well as liquid chromatography, capillary electrophoresis and flow injection with luminescence detection in the presence of these organized media are described in detail.
