摘要：

The widespread presence of humic acids (HAs) and chromium (Cr) in aquatic systems and drinking water sources is a serious threat to the environment and human being. However, no studies on the potential interaction and simultaneous removal of these two types of contaminants have been conducted. Here, a novel electro-Fenton process was reported for the effective and simultaneous removal of HAs and Cr(VI), where H2O2was in situ produced from the electro-generated H2and O2on the Pd/Fe3O4nanocatalyst surface and Fe(II) was provided from the support. We show that HAs exhibit as reductants and sorben...
