“…Consequently, there is currently a need for the development of low-cost, robust, reliable monitoring techniques that can be easily integrated into water flow systems [1]. Vibrational spectroscopic techniques, including near infrared (NIR) and mid infrared (MIR) spectroscopy, have been proposed as potential tools to improve the speed and reduce the cost of water quality testing [2]. Such techniques have become standard quality analysis tools in the food and pharmaceutical industries, in which they are commonly implemented as process analytical technologies for continuous quality monitoring.…”

“…Vibrational spectroscopy comprises a group of methods that may be applied for monitoring water quality. Among the broad spectrum of techniques belonging to this family, to date Fourier Transform Infrared (FT-IR) and Attenuated Total Reflectance (ATR) spectroscopy in the mid infrared (MIR) wavelength range (2500 -16,000 nm) have been developed for contaminant detection in water [2]. Due to the high absorption of MIR light by water, these techniques have depended on the use of pre-enrichment steps such as solid phase microextraction.…”

This research investigates the potential of near infrared spectroscopy (NIRS) for the detection and quantification of pesticides in aqueous solution. Standard solutions of Alachlor and Atrazine (ranging in concentration from 1.25 -100 ppm) were prepared by dilution in a Methanol/water solvent (1:1 methanol/water (v/v)). Near infrared transmission spectra were obtained in the wavelength region 400 -2500 nm; however, the wavelength regions below 1300 nm and above 1900 nm were omitted in subsequent analysis due to the poor signal repeatability in these regions. Partial least squares analysis was applied for discrimination between pesticide and solvent and for prediction of pesticide concentration. Limits of detection of 12.6 ppm for Alachlor and 46.4 ppm for Atrazine were obtained.

“…The vibration bands of the groups among atoms of C, C-O, and N are seen in the spectra interval 1100-2800 cm À1 . [25] The resonant vibration bands of the groups formed by O atoms are present in the wavenumbers interval around 1000 cm À1 . In addition, in this region there are present some of the deformation vibration bands, such as CO-NO bonds.…”

The study uses the Fourier transform infrared spectroscopy method to evaluate the influence of phosphogypsum from the soil on the growth and accumulation of nutrients in Spinacia oleracea. Attenuated total reflectance spectra of Spinacia oleracea roots and stems originated from plants cultivated on 28% to 52% phosphogypsum enriched soil have been studied in the 4000-600 cm À1 area. The structure of the infrared absorption bands for spinach roots and stems and for the soil where plants were grown was analyzed. Thus, it was observed that phosphorus-oxygen bonds contribution can be identified both in roots and stems absorption spectra. The significance of the research is the possibility to use the infrared investigation as rapid technique, particularly useful for agriculture, to study the extraction and assimilation process of the compounds containing phosphorus and nitrogen from the soil in which the spinach seedlings grew. In the case of this study, it was observed that the absorption of phosphorus in the spinach roots and stems has not the same effect. The analysis of obtained data indicated that the assimilation of phosphorus from phosphogypsum enriched soil induces changes in spinach roots structure that are most likely due to an increase synthesis of proteins, rather than to a decrease in carbohydrates quantity.
