Kojima湖表层水的腐殖质特征

摘要:
Humic compounds are one of the major substances that affect the COD value of the surface water of Lake Kojima. The humic compounds in the lake water were studied with a spectrofluorophotometer. The 3-dimensional fluorescence spectrum suggests that two kinds of fluorescent substances exist in the lake water. One shows an fluorescence excitation maxim (Ex) at about 240 nm and an emission maxim (Em) at 413 nm. The other has an Ex at 330 nm and an Em at 418 nm. The former peaks are associated with humic acid and the latter peaks are associated with fulvic acid. These peak intensities are proportional to the COD values. The fulvic acid in the lake water may be enriched by the effluent from domestic water treatment plants.
