Determination of 2-methoxyphenol in model solutions by spectrophotometry / V. D. Alikova, A. P. Chernova, V. K. Shormanov, E. I. Korotkova
Язык: английский.Резюме или реферат: A spectrophotometric approach for determination of 2-methoxyphenol in model solutions has been developed. The absorption spectra of 2-methoxyphenol were determined in the wavelength range from 200 to 400 nm in solutions of 95% ethanol, acetonitrile, 0.1 M sodium hydroxide and ethyl acetate with a concentration of the −3 analyte of 0.05 mg dm . For the quantitative determination of 2-methoxyphenol, a series of solutions was prepared with various −3 −3 concentrations from 0.001mgdm to 0.05mgdm in 95% ethanol, acetonitrile, 0.1 M sodium hydroxide. The optical density of 2-methoxyphenol in solvents was measured at a wavelength of 276 nm and 289 nm. The developed method was tested using the method analysis of spiked samples..Примечания о наличии в документе библиографии/указателя: [References: 12 tit.].Тематика: электронный ресурс | труды учёных ТПУ | quantitation | 2-methoxyphenol | UV/VIS spectrophotometry | количественное определение Ресурсы он-лайн:Щелкните здесь для доступа в онлайнTitle screen
