The use of nanoparticles for environmental remediation is an emerging technology. Pioneering the field is the use of nanoscale zerovalent iron (nZVI) to cleanup ground waters contaminated with chlorinated organic pollutants. nZVI particles have already been deployed for field scale remediation their commercial production is a growth area and their application to the contaminated soil environment is a logical next step. We seek LOQ time as part of a NERC funded programme; the overall aim of which is to test the impacts of nZVIs on soil microbial communities. The specific pioneering experiments proposed here seek to establish the efficacy of small-angle neutron scattering techniques to study the agglomeration of the nanoparticles within a realistic soil matrix during the remediation process which is critical to understanding and predicting its remediation efficacy and environmental impact.
