“…This approach is similar to the one used by Sharma et al [326] to evaluate As and E. coli contamination in the India River via bioluminescent bio-reporter. For more details about the light emission spectroscopy via an optical fibre sensor platform, one can refer to the work conducted by Ibanez et al [327] and Chong et al [328].…”

a b s t r a c tWater monitoring technologies are widely used for contaminants detection in wide variety of water ecology applications such as water treatment plant and water distribution system. A tremendous amount of research has been conducted over the past decades to develop robust and efficient techniques of contaminants detection with minimum operating cost and energy. Recent developments in spectroscopic techniques and biosensor approach have improved the detection sensitivities, quantitatively and qualitatively. The availability of in-situ measurements and multiple detection analyses has expanded the water monitoring applications in various advanced techniques including successful establishment in hand-held sensing devices which improves portability in real-time basis for the detection of contaminant, such as microorganisms, pesticides, heavy metal ions, inorganic and organic components. This paper intends to review the developments in water quality monitoring technologies for the detection of biological and chemical contaminants in accordance with instrumental limitations. Particularly, this review focuses on the most recently developed techniques for water contaminant detection applications. Several recommendations and prospective views on the developments in water quality assessments will also be included.

“…In this configuration, the analyte is retained by adsorption either on a plane surface or in microbeads. In plane surfaces it is usual to deliver the analyte through the spotting of a few microliters of the sample in the support with the aid of micropipets, or through a solid-phase extraction procedure (Ibañez and Escandar, 2013). In the latter case, the active support is a membrane loaded into a stainless steel filter holder; applying a positive pressure with a syringe the sample solution is forced to pass through the disk.…”

“…When particulate materials are used in batch configurations, equilibrium is established between microbead active sites and the analyte. After either evaporating or filtering the solution in which the components were dissolved, beads are transferred to a specially designed spectrofluorimetric holding for the corresponding measurement (Ibañez and Escandar, 2013).…”

The development of Green Analytical Chemistry (GAC) methods is one of the most active areas of Green Chemistry. Especially relevant are GAC methods devoted to the detection and quantification of environmental pollutants, because they should not pollute the environment more than the analyte to be determined. While considerable attention has been paid to develop environmentally friendly alternatives for the first stage of the global analytical process (e.g., sample preparation techniques), relatively fewer works are dedicated to implement green approaches for obtaining the analytical signal. Current strategies that are based on the principles of Green Chemistry for the determination of common organic pollutants in natural waters are detailed. The review collects and discusses selected publications from about the last 5 years relating to the topic, highlighting the role of multivariate calibration as a modern and very useful tool to achieve the pursued objectives.

Chemically Tapered Multimode Optical Fiber Probe for Fluoride Detection Based on Fluorescence Quenching of Curcumin

et al. 2015

View full text Add to dashboard Cite

The present work reports a simple fluorescence based tapered fiber optic probe for fluoride ion having a detection range of 2.08 × 10 -6 -2.005×10 -4 M. The performance of the tapered probe is evaluated with respect to probes that consist of combinations of bare un-cladded multimode optical fibers. The effect of fluorescence quenching of a natural dye Curcumin in the presence of fluoride ion is used in the implementation of the probes. The probe effectively uses multiple mechanisms for the excitation and collection of fluorescence from the medium enabling higher sensitivity compared to conventional spectrophotometry especially at very low concentrations of fluoride.
