Abstract:
... Biochar-derived dissolved organic matter (DOM) plays a crucial role in controlling the interactions between pollutants and biochars. Here, we determined the compositions of DOMs extracting from biochars (BCs) and acid-modified-biochars (MBCs) at different pH using UV, 3D-fluorescence and ultra-high-resolution mass spectroscopy (ESI-FTICR MS), which allowed us, for the first time, to distinguish th ...
