Humic acids (HA) are ubiquitous redox-active compounds of natural aquatic and soil systems. Here we studied the potential of HA as reductants for chlorinated aliphatic pollutants. To avoid artifacts potentially involved when studying chemically reduced HA, we prepared electrochemi cally reduced soil, aquatic and synthetic HA, and anthrahydroquinone-2, 6-disulfonic acid (AHQDS), a model compound for hydroquinone ...
