WebThe emission spectrum was recorded between 290 and 420 nm with a 120 nm/min scanning speed. The absorption of the complex within the studied concentration range was not high enough for the correction of inner filter effects. Synchronous and 3D fluorescence spectra were recorded under similar settings. WebRecently, the combined application of spectroscopic techniques, including synchronous fluorescence spectra (SFS), ultraviolet-visible (UV–Vis), and Fourier infrared spectroscopy (FTIR), has been demonstrated to be reliable in characterizing the complexation features of DOM and HMs (Chen et al., 2015, Chen and Yu 2024).
