Professor Hocheol Song's research lab specializes in environmental remediation using advanced nanomaterials, with a primary focus on the degradation of persistent organic pollutants such as chlorinated hydrocarbons. The lab investigates the reactivity and mechanisms of nanoscale zero-valent iron and other engineered nanomaterials in reducing toxic chlorinated ethanes and related compounds in aqueous systems. Current research emphasizes optimizing reaction kinetics, understanding surface reactivity, and improving the efficiency and selectivity of nanoscale iron particles for practical environmental applications. The lab also explores the influence of solution conditions and material properties on degradation pathways and rates.

Nanosized iron (< 100 nm in diameter) was synthesized in the laboratory and applied to the reduction of eight chlorinated ethanes (hexachloroethane (HCA), pentachloroethane (PCA), 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA), 1,1,1,2-tetrachloroethane (1,1,1,2-TeCA), 1,1,2-trichloroethane (1,1,2-TCA), 1,1,1-trichloroethane (1,1,1-TCA), 1,2-dichloroethane (1,2-DCA), and 1,1-dichloroethane (1,1-DCA)) in batch reactors. Reduction of 1,1,1-TCA increased linearly with increasing iron loading between 0.01
