Fig. 5From: Impacts of hydrous manganese oxide on the retention and lability of dissolved organic matterColor-coded composite STXM maps of C (red), N (green), and metal (blue; Mn for HMO and Fe for goethite) for a HMO with initial C:Mn ratio of 0.46, b HMO with initial C:Mn ratio of 2.5, c goethite with initial C:Fe ratio of 0.23, and d goethite with initial C:Fe ratio of 3.1. Color bars are optical density ranges for each element in each specific sampleBack to article page
