Fractional Wavelet Transform for the Quantitative Spectral Analysis of Two-Component System

The fractional wavelet transform (FWT) combined with zero crossing technique was applied to the absorption spectra for the quantitative resolution of a binary mixture consisting of trimethoprim and sulfachloropyridazine sodium. The absorption spectra of trimethoprim and sulfachloropyridazine sodium were processed by FWT method. In the following step, the FWT spectra were obtained by plotting the fractional wavelet coefficients versus the wavelength. Classical second derivative method was applied to the fractional wavelet signals in the wavelet domain. A calibration graphs for each substance were obtained by measuring the FWT-amplitudes at an appropriate wavelength corresponding to a zero crossing point in the derivative spectra of the FWT-signals. The amounts of trimethoprim and sulfachloropyridazine sodium in tablets.
