Fluorescence and Raman Spectroscopy Study of Humic Acids in Iron Chloride Solutions and Magnetite/HA Nanoparticles

摘要：

　　Spectral properties of water-dispersible sorbent produced from humic acids (HA) extracted from brown coal and magneto-active nanoparticles were measured for the samples of different magnetite/HA ratio and the way of their preparation.The influence of iron (Ⅲ) ions on spectral properties of HA in aqueous solution was investigated using Stern-Volmer plots describing HA fluorescence quenching.The Stern-Volmer dependences were found to be linear at concentration of iron (Ⅲ) ions smaller 20 micromole/L and nonlinear at higher concentrations.
