- Abstract
In order to prolong the usage life of magnetite in the reduction of Cr(VI) to Cr(III), a novel magnetite-Lysinibacillus sp. system was proposed in the study. The optimal condition of the combination system was optimized. The highest Cr(VI) removal rate was obtained with glucose of 8 g/L, yeast powder of 10 g/L and pH in a range of 8-10. As compared with the reaction of magnetite and Lysinibacillus sp. respectively, enhanced effect of biological-chemical system on Cr(VI) removal was observed, contributing to the synergetic effects between magnetite and the microorganism. With cyclic immobilization method, Lysinibacillus sp. was immobilized on the surface of magnetite successfully. The column experiment showed that the engineered system could remove 400 mg/L Cr(VI) from the solution for 24 h, which indicated that the immobilized magnetite is applicable for the practical treatment of Cr(VI)-containing wastewater.
