Development of recycled aggregate bio-carrier with sulfate reducing bacteria for the elimination of heavy metals from seawater

초록

In this study, we fabricated a novel recycled aggregate (RA) bio-carrier with sulfate-reducing bacteria (SRB) for the effective removal of the heavy metals Zn2+, Ni2+, and Cr6+ from contaminated seawater. By using only RA carriers, Zn2+, Ni2+, and Cr6+ could be removed up to 35.6, 11.0, and 61.3% and SRB-immobilized RA biocarriers could effectively lead to the removal of Zn2+, Ni2+, and Cr6+ up to 100.0, 98.0, and 87.8% for 100 ppm concentration of the heavy metals at 37A degrees C, respectively. These results indicate that recycled aggregate bio-carriers with SRB hold great potential for use in the removal of cationic heavy metal species from marine environment.
