摘要
We studied the mechanism for the simultaneous removal of nitrate and Ni(II) by Enterobacter sp. CC76. Response surface methodology results showed that the maximum removal ratios of nitrate and Ni(II) were 95.02% and 75.99% under the following conditions: pH 7.37, 54.31 mgL(-1) Fe(II), and 10.00 mgL(-1) Ni(II). The mechanism of Ni(II) removal involved Fe-oxide adsorption and the increase of pH. In addition, meteorological chromatography analysis indicated that Ni(II) affected gas composition during denitrification. Scanning electron microscopy and X-ray photoelectron spectroscopy confirmed that Fe-oxide adsorption was the main contributor to Ni(II) removal. This study shows that Enterobacter sp. CC76 can enhance the adsorption of Ni(II) onto Fe-oxides while removing nitrate.
