Abstract

The determination of C fractions in lab requires prior extraction steps that are laborious and time-consuming. Ozonation chemiluminescence can avoid the problem and has been successfully used to measure the C and N compounds in air or water, thus was proposed to determine C fractions of organic materials. Twenty-six different organic materials including soil organic matter and decomposed plant roots were examined. The changes of C fractions and molecular C structures for organic materials were studied during the ozonation process. Based on the ozonation process, three independent models were set up to predict C fractions by the luminescence characteristics. During ozonation all the three atoms of ozone were synthesized to the structure of new organic matter, thus the amount of carboxyl, carbonyl, or O-alkyl increased. C fractions can be assessed by the index of power function for luminescence intensity or luminescence time. Although some uncertainty exists in the models, this methodology provides a significant step forward from the traditional lab approach.
