Montmorillonite enhances the remediation of lead (II) by polyvinyl alcohol/sodium alginate/Chlorella sorokiniana FK microcapsules
Source abstract
Abstract
Microbial remediation of heavy metals has attracted more and more attention because of its cleanliness and high efficiency. In this study, montmorillonite was used in coordination with polyvinyl alcohol and sodium alginate to prepare a new microcapsule of living Chlorella sorokiniana FK, and its remediation effect on Pb(II) was investigated. The results showed that the introduction of montmorillonite enhanced the mechanical strength of microcapsules and the removal efficiency of Pb(II) (100 %). The staining results of live/dead cells further indicated that the introduction of montmorillonite can more effectively help Chlorella sorokiniana FK in microcapsules resist lead stress. In addition, the characterization results proved that microcapsules can concentrate Pb(II) on the surface through electrostatic attraction, surface complexation, and ion exchange, and then transform them into mineralized precipitates (Pb 5(PO 4) 3Cl and Pb 3(CO 3) 2(OH) 2) through the surface precipitation and induced carbonate precipitation of internal microalgae. It is worth noting that pot experiments have shown that the prepared microcapsules can more effectively reduce the bioavailability of lead and improve the structure and function of microbial communities. This study indicates that the prepared microcapsules have great potential for application in heavy metals remediation.
