Abstract:
The aim of this work was to verify the influence of filtration processes on water structure detected through spectral variations in water absorbance pattern in near infrared region. Samples of water before and after 5 types of filtrations were analyzed. NIR spectra were collected in transmission mode in the whole NIR range, by using minispectrometer Hamamatsu (TG – Cooled NIR-IC9913GC, Hamamatsu, Japan). NIR data were processed using Pirouette software (ver. 4.5, Infometrix, USA). Different water absorbance patterns corresponding to different stages of filtrations are for better visual representation presented in the form of aquagrams [1]. The results of analysis showed that NIR spectral pattern of water clearly show changes in hydrogen bonds network resulting from the effects of filtration processes. The obtained results show potential of near infrared spectroscopy for detection and monitoring changes in water under mechanical perturbations.
