三维荧光技术在天然水质表征中的研究进展

Research Progress of Natural Water Quality Characterization Using Three-Dimensional Fluorescence Technology

三维荧光技术在天然水质表征中有独特的应用潜力。根据已有的研究成果,对近10年来三维荧光技术在天然水质表征方面的应用进行总结。天然水中主要存在6个荧光峰:腐殖酸类荧光峰即PeakA,PeakC及PeakM;类蛋白荧光峰即PeakB,PeakT1及PeakT2。根据各类荧光峰的差异可以分辨出不同来源的水样,同时可以反映出人类活动、微生物活性及浮游植物对于天然水质的影响。此外,pH,温度和金属离子等环境因素也对荧光产生影响。

Three-dimensional fluorescence technology has been found to have an unique potential application in characterization of natural water quality.According to the reported researches in recent ten years,a summary has been made on the application of three-dimensional fluorescence in characterization of the natural water quality.In the na-tural water,there are mainly six fluorescence peaks,namely,humic acid-like fluorescence peaks such as Peak A,Peak C,and Peak M;protein-like fluorescence peaks such as Peak B,Peak T1,and Peak T2.Three-dimensional fluorescence technique can distinguish water samples in different sources and reflect the effect of human activity,microbial activity and phytoplankton in natural water.Additionally,the environment factors,including pH,temperature,metal ions can also affect the fluorescence response.
