| Abstract: | AbstractPhoto-oxidation of dissolved organic matter in saline and non- saline samples is monitored by measurement of residual fluorescence intensity. For fulvic acids, the method has a detection limit of 0.005 mg C L?1, and maximum photo-oxidation is achieved with H2O2 oxidant and a low-intensity UV source. |
