- Abstract:
- Fluorescent organic matters in water can be detected rapidly and conveniently by using 3D fluorescent technique. Sixty-nine organic matters in Environmental Quality Standards for Surface Water (GB 3838-2002) were detected by using 3D fluorescent technique, and 18 kinds of organic matters had 3D fluorescence. At a certain concentration range, the characteristic fluorescence peak of the orgnaic matter increased with its concentration increasing, and there was a strong linear relation between fluorescence intensity and organic matter concentration (R2>0.95). Accordingly, quantitative analysis of fluorescent organic matters by 3D fluorescence technique could be realized. By analyzing the position of fluorescence peak in the 3D fluorescent spectrum, it could be found that the fluorescence characteristic of organic matter was related to its molecular structure. As a result, it was convenient to classify the fluorescent organic matter and qualitatively analyze the pollution of a water body by fluorescent organic matter.
