Contaminated Sediments'

Application of Nanoscale Zero-Valent Iron Technology for Treatment of
Contaminated Sediments    The University of New South Wales UNSW Water
Research Centre   Two APAI PhD scholarships are available via an ARC Linkage
grant (2011 - 2013) to investigate the treatment of benthic sediments
contaminated with chlorinated organic compounds using nanoscale zero-valent iron
technology.  Research into innovative treatment technologies for contaminated
sediments is especially relevant to Australia, where natural waterways offer
significant value in terms of natural beauty, heritage, recreational use, and
commercial and industrial importance. The UNSW Water Research Centre, in
collaboration with private, public, and international partners, has recently
commenced a three-year ARC Linkage project building upon its previous work on
the application of nanoscale zero-valent iron (nZVI) for environmental
remediation.  The intended outcomes of this project are the synthesis of
supported nZVI particles for the in situ remediation of contaminated sediments,
and the evaluation of their ability to degrade selected organic contaminants
under conditions typical of benthic sediments.  Studies will be designed to
gain an understanding of the fundamental mechanisms and processes that influence
contaminant degradation by nZVI particles in order to determine the most
effective methods for synthesis and application in sediment environments.  The
performance of supported nZVI particles for in situ remediation of contaminated
sediments will be evaluated through targeted field trials.  Given recent work
by partner organisations on the application of activated carbon for the
treatment of contaminated sediments, it is expected that research will focus on
activated carbon supported nZVI particles, though other methods for particle
stabilisation and/or supports may be considered
