Luminescence characteristics for different compositions of organic matter in soil and sediment ozonation

The real-time monitoring of soil quality and marine environment needs fast and accurate determination of organic matter compositions, which is difficult to realize. Ozonation has been successfully used to determine the concentrations of organic matter, thus we'll explore the possibility of determining the compositions of organic matter by ozonation. The luminescence characteristics for different compositions of organic matter were studied after the soil and sediment organic matter were divided into lipids, acid soluble fractions (AS), and acid insoluble fractions (AIF). Results showed that 1) the luminescence characteristics for soils and sediments are highly correlated with both concentrations of AS and AIF; 2 the relationship between AS and the luminescence characteristics is different from that between AIF and the luminescence characteristics; 3) lipids, AS, and AIF have different luminescence characteristics, and their concentrations can explain the different luminescence characteristics among soils and sediments. The paper first illustrated why different soils and sediments have different ozonation luminescence characteristics, suggesting that ozonation can be used to determine organic matter compositions. These results make real-time monitoring of the soil quality and marine environment feasible.
