Synthesis and Characterization of Green Tea - Zero Valent Iron (GT-ZVI) Nanoparticles for Ground Water Remediation
Conference Year
January 2019
Abstract
Zero valent iron (ZVI) has been studied and utilized as an environment friendly, inexpensive, reactive agent to remove various aqueous organic/inorganic contaminants. The major drawback of ZVI nanoparticles is that they are readily oxidized under an oxygen rich environment. To overcome this drawback, I encapsulated the ZVI nanoparticle in an anti-oxidant coating, which inhibits ZVI surface oxidation. The anti-oxidant of choice, Green Tea (GT), is a well-known anti-oxidant with high polyphenol content. The Green Tea coating material revealed that the ZVI nanoparticles can be activated “on demand” to produce either reductive (in the absence of oxygen) or oxidative reactions upon exposure to an accelerant, which is desirable for removing and degrading various ground water contaminants. The presentation will explore GT-ZVI synthesis and various characterizations, such as pH, size, magnetic activity, and more.
