    RP-HPLC and UV Spectrophotometric Analysis of Paracetamol, Ibuprofen and Caffeine in Solid Pharmaceutical Dosage Forms by Derivative, Fourier and Wavelet Transforms: A Comparison Study
    Research 2020 : July - September

    Different signal-transforming algorithms were applied for UV spectrophotometric analysis of paracetamol, ibuprofen, and\ncaffeine in ternary mixtures. Phosphate buffer pH 7.2 was used as the spectrophotometric solvent. Severe overlapping spectra\ncould be resolved into individual bands in the range of wavelengths 200-300nm by using Savitzkyâ??Golay smoothing and\ndifferentiation, trigonometric Fourier series, and mother wavelet functions (i.e., sym6, haar, coif3, and mexh). To optimize spectral\nrecoveries, the concentration of various types of divisors (single, double, and successive) was tested. The developed spectrophotometric\nmethods showed linearity over the ranges....................
