FORMATION OF REFRACTORY ORGANIC CARBON IN BOTTOM SEDIMENT

Abstract

 Carbon fixation by marine plants such as eelgrass has been the main focus of research on the blue carbon effect in coastal areas. In this study, we collected organic sediment from the seafloor with excessive organic matter and conducted experiments on the persistent degradation of organic matter by coal ash granules (GCA). The results suggested that the ions leached from GCAs promoted the reduction of COD, but also formed refractory organic carbon.
