Pyrochars as promising soil ameliorants: Assessment of content and spectral properties of their lipid fractions by E.V. Smirnova, К.G. Giniyatullin, А.А. Valeeva, Е.S. Vaganova

“…Their spectra in the UV-visible range are characterized by an exponential increase in the absorption intensity with a decrease in the wavelength, on which individual absorption maxima of groups of individual compounds are superimposed. Using the methods of empirical modeling of the spectral regions, it has been shown that the low-temperature pyrolysis of woody and herbaceous material results in the multi-molecular pool of organic compounds soluble in the alcohol- benzene mixture. …”
