UV-VISIBLE SPECTRAL ANALYSIS OF BORIC ACID IN DIFFERENT SOLVENTS: A CASE STUDY

摘要

Boric acid is one of the widely used inorganic compound in pharmaceutical industry. We find its utilization as an antiseptic, in eye wash preparations, as an insecticidal, as a buffering agent etc. In this present work, a comparative study of the UV-Vis spectras of the boric acid solution in different solvents have been done. A variety of solvents like water, ethanol, methanol, glacial acetic acid, hexane, Tetrahydrofuran and 0.2M HCl solution have been employed for spectral analysis. When water was taken as a solvent, aqueous boric acid solution gave negative absorbance in complete range of UV-Vis analysis i.e. 1100nm to 190 nm. In contrary to this, when methanolic solution of boric acid was taken, positive absorbance in the complete range of spectrum was noticed. Purely on the basis of spectras obtained for boric acid solution in different solvents, best solvent out of those have been regarded as the most suitable solvent for carrying out the UV-Vis analysis for boric acid
