Abstract

The development of convenient and effective permeable reactive barriers (PRBs) for groundwater remediation is of highly interest. Self-powered removal of phenol using a redox fuel cell as a feasible PRB reactor system was presented in this work. This system can employ Fe species in water with a high oxidation state Fe(III) acting as an oxidant in the cell, and Fe(III) can be easily regenerated by the oxidation of Fe(II) by oxygen. The results showed that the open circuit potential (OCP) was 0.39 V, and the maximum power density of the cell is 312 mW m−2 with the current density of 1669 mA m−2 in phenol-Fe(III) cell. Meanwhile, the degradation of phenol was observed. Furthermore, in order to test cell’s performance conveniently, phenol-Cr(VI) cell was assembled due to much toxic and highly oxidizing Cr(VI). The absolute removal amounts of Cr(VI) and phenol were 298 mg L−1 and 528 mg L−1, after ca. 60 h running, respectively. It is expected that the self-powered pollutants removal system could be a promising candidate for the application of PRBs in groundwater remediation.
