Reductive dechlorination of octachlorodibenzo-p-dioxin by nanosized zero-valent zinc: Modeling of rate kinetics and congener profile

► Rapid degradation of OCDD by zinc nanoparticles under ambient conditions. ► Congener profiles from sequential dechlorination agree with LFER-model predictions. ► Toxicity (TEQ) values calculated for OCDD degradation process. ► First report on OCDD degradation using zero-valent nanoparticles.
