Abstract:

Fourier deconvolution and second-derivative spectroscopy have been used to enhance the resolution of infrared spectra of humic acid (HA) extracted from dried municipal waste. The results demonstrate the extent to which the use of such resolution enhancement techniques can disclose new valuable information concerning the composition of complex heterogeneous samples. The findings are in good agreement with previously obtained solid-state NMR results.
