EVIDENTIAL CHROMATE BIOREDUCTION BY CAPILLARY ZONE ELECTROPHORESIS

EVIDENTIAL CHROMATE BIOREDUCTION BY CAPILLARY ZONE ELECTROPHORESIS

The capacity of Serratia marcescens culture, both in planktonic cultures and in activated carbon biofilm, to reduce chromium(VI) to insoluble chromium(III) was evaluated at different times by capillary zone electrophoresis (CZE). The simultaneous determination of both chromium species by CZE made ev...
