Enhancement of stability and reactivity of nanosized zero-valent iron with polyhydroxybutyrate
Original language description
Polyhydroxybutyrate (PHB) is a bacterial storage polyester, which is produced directly in the activatedsludge process. In the present study, PHB was tested as a scaffold material for stabilization ofnanosized zero-valent iron (nZVI). The morphology of the resulting composite was assessed usingtransmission electron microscopy (TEM) and scanning electron microscopy (SEM) coupled withenergy-dispersive X-ray spectroscopy (EDX) analysis. In addition, the surface chemistry and particlestabilities of nZVI and nZVI/PHB were determined with zeta potential analysis and disc centrifugemeasurements, respectively. Moreover, the sedimentation rate of bare nZVI was tested and comparedwith that for nZVI/PHB. Batch experiments further confirmed that nZVI/PHB particles arenot only more stable but also more reactive toward perchloroethene (PCE) and Cr(VI) in comparisonwith the bare nZVI. These results suggest that PHB can be developed as an inexpensive and environmentallyfriendly material for the stabilization of nZVI particles.
