Nanoscale Zerovalent Iron Particles for Groundwater and Soil Treatment: Monitoring and Control of their Solid- State Synthesis, Stability, and Activity

Popis výsledku v původním jazyce

In the last two decades, zerovalent iron nanoparticles (nZVI) has been established as a multifunctional material exhibiting wide applicability in the large-scale remediation of surface water with microbial contamination, groundwater in sediments, and soils at localities contaminated by various inorganic and organic hazardous substances. This chapter summarizes the key techniques applicable for nZVI characterization, including the in situ monitoring of nZVI synthesis. It presents the comparison of two standard sophisticated laboratory techniques with one, newly invented, technique to quantify the Fe0 content in aqueous slurries. These three techniques were used to monitor the ageing process of nZVI dispersions stored under various conditions. The ageing process of selected samples of nZVI particles, stored in their aqueous dispersions, was monitored using three key experimental techniques: X-ray diffraction (XRD), Fe Mossbauer spectroscopy, and optimized acid digestion accompanied by hydrogen evolution. High-temperature X-ray diffraction (HT-XRD) plays a significant role in the study of the transformation and synthesis processes of materials.
