Dechlorination of dichlorodiphenyltrichloroethane (DDT) by Fe/Pd bimetallic nanoparticles: Comparison with nZVI

Kubra Ulucan-Altuntas, Eyup Debik

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 1, doi: 10.1007/s11783-019-1196-2

Abstract: The oxidation effect of nZVI on DDT is greatly improved when Pd is dopped.The dechlorination of DDT is more like to DDE via Fe/Pd but to DDD via nZVI.Degradation products concentrations are lowered via Fe/Pd when compared with nZVI.synthesized using the catalytic element palladium to increase the effect of nano zero valent iron (nZVI), in the light of the information obtained from our previous study, in which the nZVI synthesis method

Optimizing synthesis conditions of nanoscale zero-valent iron (nZVI) through aqueous reactivity assessment

Yanlai HAN,Michael D. Y. YANG,Weixian ZHANG,Weile YAN

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 813-822 doi: 10.1007/s11783-015-0784-z

Abstract: Nanoscale iron particles (nZVI) is one of the most important engineered nanomaterials applied to environmentalIn this study, four reaction parameters were adjusted in the preparation of borohydride-reduced nZVI.The results confirm that the reductive reactivity of nZVI is most sensitive to the initial concentrationSolution mixing speed, in contrast, carries a relative small weight on the reactivity of nZVI.Additional insights including the structural and chemical makeup of nZVI can be garnered from Cu(II)

Nanoscale Zero-Valent Iron (nZVI) for Heavy Metal Wastewater Treatment: A Perspective

Shaolin Li,Lei Li,Weixian Zhang,

Engineering doi: 10.1016/j.eng.2023.08.012

Abstract: Among such initiatives, treatment using nanoscale zero-valent iron (nZVI) is one of the best developedWhile nZVI is already well known for its site-remediation use, this perspective highlights its applicationWe demonstrate several advantages of nZVI in this wastewater application, including its multifunctionalitycapture and enrich metal(loid)s at low concentrations (with a removal capacity reaching 500 mg·g–1 nZVIIt is concluded that nZVI is a potent reagent for treating HMW and that nZVI technology provides an eco-solution
