Abstract
A novel approach to Cr(VI)-contaminated
wastewater treatment was investigated using microbial
fuel cell technologies in fed-batch mode. By
using synthetic Cr(VI)-containing wastewater as
catholyte and anaerobic microorganisms as anodic
biocatalyst, Cr(VI) at 100 mg/l was completely
removed during 150 h (initial pH 2). The maximum
power density of 150 mW/m2 (0.04 mA/cm2) and the
maximum open circuit voltage of 0.91 V were
generated with Cr(VI) at 200 mg/l as electron
acceptor. This work verifies the possibility of simultaneous
electricity production and cathodic Cr(VI)
reduction.
