Determination of sodium borosilicate bands in IR spectrum of multi-component batch

A borosilicate mixture obtained in an aqueous medium has been studied by IR spectroscopy. A technique has been developed for determining the individual bands of sodium borosilicate in the presence of the most probable impurities - boric and silicic acids, borate and sodium silicate. The technique is based on calculating the absolute degree of difference between wave numbers and band intensities. It was found that some of the bands of the five-component mixture are indistinguishable in their position in the IR spectrum and intensity and are unsuitable for analysis. The bands at 653, 1164, 3300, and 3729 cm ^-1 are indistinguishable in wavenumbers, but differ in intensities, so they can be conditionally applicable for identifying sodium borosilicate.
