Spectroscopic characterization of humates isolated from from different soil types
Original language description
Two optical metods (UV-VIS and SFS) were used. Five Czech soil humates samples (Leptic Cambisol, Haplic Cambisol, Eutric Cambisol 1-arable soil, Eutric Cambisol 2-grassland, Haplic Chernozem) were compared. Absorbance in spectral range 300-700 nm was measured using optical fiber on spectrometer Varian Cary 50 Probe. Fluorescence spectra (SFS) within the range 255-655 nm were measured by spectrofluorimeter Aminco Bowman. From UV- VIS spectra colour indexes (Q4/6) were determined. Fluorescence indexes (F)were calculated from SFS spectra as a ratio RFI468/RFI522. The same main fluorophore was observed in all soil humates. Samples were also compared using parameters of humic substances quality, carbon content, fluorescence and colour indexes.
