Facile one step green synthesis of iron nanoparticles using grape leaves extract: textile dye decolorization and wastewater treatment
The existing knowledge on the reactivity of green iron particles on textile dye and wastewater decolorization is very limited. In this study, the potential of green iron particles synthesized using grape leaves extract on reactive dye (reactive red 195, reactive yellow 145, reactive blue 4 and react...
