|Beschreibung||The injection of metal nanoparticles has emerged as a promising technique for the remediation of contaminated aquifers. In particular, iron nanoparticles have received much attention due to their improved reactivity with regard to contaminants. Field studies have demonstrated a faster degradation of pollutants following the injection of iron particles, when compared to other remediation techniques. Although the technique is promising, there are substantial concerns about particle delivery paths that require the development of monitoring methods with enhanced spatial-temporal resolution capable of providing information about fate and transport of the injected particles. Spectral induced polarization (SIP) measurements are known to provide a strong response in the presence of metallic nanoparticles. In this project, the SIP signature of metal nanoparticles will be determined using measurements on suspensions and packed soil columns. In addition, the ability to monitor the fate and transport of metallic nanoparticles will be test in laboratory flow experiments in 1-m long laboratory soil columns.|
