Direct measurement of the fluorescence characteristics of aquatic humic substances by three-dimensional fluorescence spectrophotometer

摘要

Humic substances play an important role in the transport of trace metals and insoluble- organic materials. They are also considered to be precursors of trihalomethane in aqua- tic environments. The direct measurement of humic substances was carried out with a three-dimensional fluorescence spectrophotometer after filtering natural-water samples through a GF/F glass fiber filter.
