摘要：Bioelectrochemical systems (BESs) were first operated in microbial fuel cell mode for recovering Cu(II), and then shifted to microbial electrolysis cells for Cd(II) reduction on the same cathodes of titanium sheet (TS), nickel foam (NF) or carbon cloth (CC). Cu(II) reduction was similar to all materials (4.79-4.88 mg/L h) whereas CC exhibited the best Cd(II) reduction (5.86 +/- 0.25 mg/L h) and hydrogen evolution (0.35 +/- 0.07 m(3)/m(3) d), followed by TS (5.27 +/- 0.43 mg/L h and 0.15 +/- 0.02 m(3)/m(3) d) and NF (4.96 +/- 0.48 mg/L h and 0.80 +/- 0.07 m(3)/m(3) d). These values were higher than no copper controls by factors of 2.0 and 5.0 (TS), 4.2 and 2.0 (NF), and 1.8 and 7.0 (CC). These results demonstrated cooperative cathode electrode and in situ deposited copper for subsequent enhanced Cd(II) reduction and hydrogen production in BESs, providing an alternative approach for efficiently remediating Cu(II) and Cd(II) co-contamination with simultaneous hydrogen production.
