Spectral, luminescent and photochemical properties of humic acids with different genesis of organic raw materials

[摘要] Spectral-luminescent properties of different samples of humic acids (HAs) are investigated. The samples of HAs fractions were obtained from Fluka Chemical Co, prepared from peat of Western Siberia region, other HAs and lignins were isolated from Arkhangelsk Region. The comparative analysis of these HAs with the sample of humic acids allocated from brown coal is carried out. The presence in the solution of herbicide 2,4-dichlorophenoxyacetic acid the humic acids has a significant effect on the processes of photochemical degradation under the action of light from an excilamp.
