摘要
提出了一种快速、现场分析沉积物和土壤中有机物的方法。对臭氧与沉积物和土壤中的有机物发生氧化反应过程中的发光规律进行了研究,利用原理试验样机测出了发光规律曲线,根据发光曲线分析了沉积物和土壤中对应的有机物含量和特征,如活性有机碳、难氧化的有机物等。通过与现有检测方法相比较,验证了使用臭氧氧化发光原理分析沉积物和土壤中有机物的有效性。根据实验中得到的不同沉积物和土壤的氧化发光特征有很大区别的现象,提出了建立土壤特征编码"土壤指纹"的概念。
A method for rapid analysis on-site of organic matter in sediment and soil is recommended. It is based on researches on the phenomenon of chemiluminescence of organic matter in sediment and soil reacting with ozone. A curve of chemiluminescence regularity was obtained by using an experimental prototype instrument, and used to analyze content and characteristics of the organic matter in sediment and soil, suchas active organic carbon, hardly-oxidized organic matter, etc. Effectiveness of the method was verified comparing its results with those of the existing detection method. Based on the finding that sediments and soils varied sharply in chemiluminescence feature from type to type, a concept of ＂soil fingerprint＂ or coding of soil properties is recommended.
