合成染料是持久性有机环境污染物,可对生物和整个生态系统造成广泛破坏。成本效益高,可持续,和有效的策略来处理这种类型的污染是必要的,因为它通常抵制传统的水处理方法。使用叶子的水提取物合成的银纳米颗粒(AgNPs),茎,和银合欢(Leucena)的果实通过UV-vis产生并表征,TEM,EDS,SDL,XPS,XRD,和zeta电位,并且证明它们能够促进吸附以修复水中的亚甲基蓝和柠檬黄污染。进行纳米修复并且不需要直接暴露于阳光或任何特殊的灯或特定的还原剂。使用叶子提取物产生的AgNP在纳米修复中表现出最佳性能,并且还表现出超过丁基化羟基甲苯(BHT)的抗氧化活性。因此,它是一种有趣的纳米工具,用于染料纳米修复和/或作为抗氧化剂纳米结构。
Synthetic dyes are persistent organic environmental pollutants that can cause extensive damage to living beings and to the ecosystem as a whole. Cost-effective, sustainable, and efficient strategies to deal with this type of pollution are necessary as it commonly resists conventional water treatment methods. Silver nanoparticles (AgNPs) synthesized using the aqueous extract from the leaves, stem, and fruits of Leucaena leucocephala (Leucena) were produced and characterized through UV-vis, TEM, EDS, SDL, XPS, XRD, and zeta potential, and they proved to be able to promote adsorption to remediate methylene blue and tartrazine pollution in water. The nanoremediation was performed and did not require direct exposure to sunlight or any special lamp or a specific reduction agent. The AgNPs produced using the extract from the leaves exhibited the best performance in nanoremediation and also presented antioxidant activity that surpassed the one from butylated hydroxytoluene (BHT). Consequently, it is an interesting nanotool to use in dye nanoremediation and/or as an antioxidant nanostructure.
