Abstract

In this paper we present a comparative evaluation of green and semi-green synthesis methods. The former utilized coffee, green tea and Virginia creeper leave extracts, the latters were based on sodium dithionite and sodium borohydride. nZVI synthesis was done in untreated tap water at room temperature to reduce the environmental footprint of the process. nZVI performance was assessed on the basis of time- dependent oxidation/reduction potential measurements and by the reductive dehalogenation of volatile chlorinated organics.
