Electron Transfer Capacities of Dissolved Organic Matter Derived from Swine Manure Based on Eletrochemical Method

Dissolved organic matters (DOM) from different stage composts were extracted, and their electron-donating and accepting capacities (EDC, EAC) were determined by an electrochemical method. Chemical structures of DOM were investigated by FTIR and PARAFAC. The objective of this paper is to understand the mechanism of the effects of chemical structures of DOM on their EDC and EAC.
