Fluorescence analysis of Cu(II), Pb(II) and Hg(II) ion binding to humic and fulvic acids
Original language description
Various methods and techniques have been used for studying humic substances binding to metal ions, among which steady-state fluorescence spectroscopy has proven to be one of the most promising and productive. The aim of this work was study molecular andquantitative analysis of metal ion binding to humic substances (HS). The object of our study was two standards of humic substances (Elliott Soil standard HA 1S102H and Elliott Soil standard FA 2S102F). All samples of IHSS standards HS were characterizedby elemental analysis (EA), ultraviolet-visible spectroscopy (UV/Vis), Fourier transform infrared spectroscopy (FTIR) and steady-state fluorescence spectroscopy. UV/Vis spectra of aqueous solutions HS were measured by spectrophotometer Hitachi U-3900 inthe wavelength range of 200?900 nm. Absorption coefficients (EET/EBz and E465/E665) of HS were calculated from the absorbance values. Infrared spectroscopy is a useful technique in characterization of structure, functional groups and form
