“…Furthermore, this technology promotes the contaminant degradation, rather than its phase transfer. Concerning PRB based on physical-chemical processes, zero-valent iron (ZVI), activated carbon and natural and synthetic zeolites, have been widely applied (Accardi et al, 2012;Baric et al, 2012;Piscitello et al, 2020;Rossi et al, 2021). ZVI is the most frequently employed reactive media, especially for the treatment of chlorinated hydrocarbon plumes, referring in particular to chlorinated ethenes and ethanes (Odziemkowski et al, 1998;Furukawa et al, 2002).…”
