6 mm, 250 mm) and a mobile phase of Methanol: chloroform (25:75) and 1 mM acetic Fig (4):- Spectrum of paracetamol standard in seconed methods
4 Simultaneous estimation of ibuprofen and paracetamol by UV spectroscopy
The method based on the induced spectral changes ASSAY OF PARACETAMOL TABLETS Acetaminophen (C8H9NO2) (B
Take a quantity of the powder equivalent to 0
this is your standard concentration
To analyze them by conventional UV-Vis method, we must often extract specific substance Beer's law is obeyed in the concentration range of 4-350 μgml−1 at 490 nm
in the range of calibrations, were added and then the solutions were diluted to 10 ml with methanol: 0
Ab initio calculations of its equilibrium geometry and vibrational spectra were carried out for spectrum interpretation Area under curve method includes determination of area of paracetamol and nabumetone at absorption maxima, which for paracetamol was 248
The flask was then filled up to the mark with 0 of NaOH and inverted twenty times to ensure the product had fully dissolved and had an even distribution
