Özet
In this paper, rapid and precise first-derivative UV spectrophotometric assay procedures are described for the simultaneous determination of methylene blue, hexamethylene tetramine and resorcinol in their binary mixtures. The methods have been applied successfully to a dragee containing methylene blue-hexamethylene tetramine and a mouth-wash formulation containing methylene blue-resorcinol combinations. The relative standard deviation was found to be 0.71% for methylene blue at 273.0 nm and 0.70% for hexamethylene tetramine at 221.3 nm in the first combination and 0.21% for methylene blue at 300.0 nm and 0.54% for resorcinol at 260.4 nm in the second combination. © 1992.
