Determination of Ibuprofen and Paracetamol in Binary Mixture Using Chemometric-Assisted Spectrophotometric Methods
Three methods are presented for simultaneous determination of ibuprofen and paracetamol without previous separation. The first method depends on first derivative UV spectrophotometry, with zero-crossing measurement. The first derivative amplitudes at 230 and 290 nm were selected for the assay of ibuprofen and paracetamol, respectively. The second method depends on first derivative of the ratio-...
متن کاملDetermination of Metoprolol and Felodipine in Binary Mixture Using Chemometric- Assisted Spectrophotometric and High-Performance Liquid Chromatographic-UV Mmethods
Four methods were developed for simultaneous determination of metoprolol and felodipine without previous separation. In the first method both drugs were determined using first derivative UV spectrophotometry, with zero crossing measurement at 222 and 235 nm for metoprolol and felodipine, respectively. The second method depends on first derivative of the ratios spectra by measurements of the amp...
متن کاملDetermination of Amlodipine and Valsartan in Binary Mixture Using Derivative- Ratio Spectrophotometric, Chemometric and High Performance Liquid Chromatographic-UV Methods
Three methods were developed for simultaneous determination of amlodipine and valsartan without previous separation. The first method depends on first derivative of the ratios spectra (DD1) by measurements of the amplitudes at 234.5 and 247 nm for amlodipine using 30μg/mL of valsartan as a divisor and at 282 and 292 nm for valsartan using 80μg/mL of amlodipine as a divisor. Calibration graphs w...
متن کاملSimultaneous spectrophotometric determination of paracetamol, phenylephrine and chlropheniramine in pharmaceuticals using chemometric approaches
BACKGROUND AND THE PURPOSE OF THE STUDY The linear multivariate calibration models such as principal components regression (PCR) and partial least squares regressions (PLS1 and PLS2) due to the mathematical simplicity and physical or chemical interpretability are sufficient and generally preferred method for analysis of multicomponent drugs. In this study, simultaneous determination of paraceta...
متن کاملUV Spectrophotometric Simultaneous Determination of Paracetamol and Ibuprofen in Combined Tablets by Derivative and Wavelet Transforms
The application of first-order derivative and wavelet transforms to UV spectra and ratio spectra was proposed for the simultaneous determination of ibuprofen and paracetamol in their combined tablets. A new hybrid approach on the combined use of first-order derivative and wavelet transforms to spectra was also discussed. In this application, DWT (sym6 and haar), CWT (mexh), and FWT were optimiz...
