Outline of Final Research Achievements

Natural organic matters in deep groundwater have distinct origns from those of NOMs in surface environments and exhibit rather different properties. In this research physicochemical properties of NOMs extracted from deep sedimentary groundwater are assessed by cluster analysis. Metal binding and redox properties of the NOMs are also investigated by potentiometry, X-ray absorption spectroscopy and bulk electrolysis with a mediator. The obtained results are compared to the corresponding results for surface NOMs to discuss how differences in origins of NOMs affect their various properties.
