Green Remediation of Hexavalent Chromium Using Naturally Derived Flavonoids and Engineered Nanoparticles

Omowunmi A. Sadik, Veronica Okello, Francis Osonga, Marcells A. Omole and Isaac K’Owino, Department of Chemistry, Center for Advanced Sensors and Environmental Systems, State University of New York at Binghamton, Binghamton, NY, USA

Conventional methods (e.g., bioremediation and zerovalent iron (ZVI)) for in situ remediation of chlorinated organic solvents may produce undesirable by-products and the use of nanoscale bimetallic particles has succeeded in eliminating some of these by-products. Palladium nanoparticles (PdNPs), bimetallic particles, ZVI particles with various oxidants, reductants, and nutrients have been shown ...
