- Description
- In this study, a novel form of zero valent iron nanoparticle (GMP-nZVI) was successfully synthesized using mango peel extracts. Iron on the surface of the synthesized particle was negligible. Surface structure and compositional analysis was carried out using XPS and FTIR whereby the characteristic feature of the analysis highlighted the role of few organic compounds in the synthesis of GMP-nZVI. Depth profiling of GMP-nZVI by XPS indicated increasing intensity of Fe0 while the portion of Fe+2/Fe+3 and the dominant species which were on the surface (i.e. C and O) were decreasing. The structural form of GMP-nZVI has a layer of polyphenol followed by the oxides and hydroxides of iron onto the metallic iron which has a shell structure of 'Fe+3/Fe+2-polyphenol' complex islands on the core metallic iron (graphical abstract). The use of mango peel in the synthesis is a low cost approach and economically viable which also provides new insight of waste recycling and nanoremediation.
