Degradation of allura red dye using Fe-Zn metal nanoparticles obtained by phytosynthesis method.
Published online by Cambridge University Press: 27 October 2020
Abstract
In the present work, the photocatalytic activity of metal Fe-Zn nanoparticles was evaluated through the degradation of the synthetic AZO colorant allura red. A Phytosynthesis method developed here takes advantage for the first time of the plant extract of Hydrocotyle ranunculoides as the reducing agent. A fitted Folin-Ciocalteu assay showed about 40% of total polyphenolic compounds used in the nanoparticles generation. UV-Vis and TEM analysis allowed identification of the nanoparticles as oxides of Fe and Zn. Finally, during measurement of the photocatalytic activity a load of 0.5 g/L was applied on a 15 μM solution of allura red as standard model pollutant, while environmental oxygen was used as the initiating agent. Tests showed a 66% degradation of the azo-type dye obeying a degradation kinetics of the first order after short times.
