Hexavalent chromium (Cr(VI)) is a well-known carcinogen, which must be completely removed from the contaminated water or reduced to a less toxic state. In this work, a bio-electrochemical platform combining electrokinetics (EK) and microbially induced calcite precipitation (MICP) was assembled to enhance Cr(VI) removal from the stocking solution. The chromate was removed mainly by the chemical precipitation of CaCrO4 and further immobilized by CaCO3 produced from the microbial bio-mineralization in the bioremediation. The coupling method was pr...
