Spectroscopic Analysis of the Boric Acid and Salicylic acid-Boric acid-Ethanol Solution

Abstract

In the present study, the vibrational analysis of boric acid molecule and boric acid solution prepared as a magistral ear drug was experimentally performed and its chemical characteristics was examined for the first time using FT-IR and NMR chemical shift spectra. The boric acid and salicylic acid powders were analyzed by X-ray powder diffraction. The particle size of boric acid and salicylic acid were determined as 457 µm in Dv(50) and 59.8 µm in Dv(50) respectively using particle size analysis device. The optimized molecular structure, vibrational wavenumbers and the highest and the lowest occupied molecular orbital analyses of boric acid molecule were theoretically obtained with DFT method at the B3LYP/6-311++G(d,p) basis set. The vibrational wavenumbers were found to be consistent with the literature results and the experimental data obtained in the current work. Boric acid solution was found to exhibit antimicrobial activity after the agar disk diffusion and agar well diffusion tests performed on Candida albicans (ATCC 10231) strain.

Paper Strip Based on Nanoemulsion of Curcumin as Boric Acid Detection

“…Peak of 883 cm -1 confirmed the asymmetric B-O bands in BO4, peak of 704 cm -1 was responsible as symmetric B-O bands in BO4, and the peak of 544 cm -1 belongs to boric acid of H3BO3. This is in accordance with the report of Öge and Keskiner[44].…”
