This study explored the potential use of apple peel extract (APE) for the biosynthesis of iron nanoparticles (FeNPs). The synthesized APE-FeNPs were characterized by UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), and transmission scanning electron microscopy (TEM). The biosynthesis of APE-FeNPs was confirmed with polyphenol peaks (237 nm, 272 nm) detected as biological components integrated into APE-FeNPS, and FTIR analysis profiled the presence of primary functional groups (OH-, NH-, CH- bending vibrations). The APE-FeNPs formed were elliptical and spherical shaped, measuring 50 nm. Treatment of malachite green dye with APE-FeNPs showed 71.51% dye decolorization within the first 1 min. This study has shown that apple peel extract can be used to synthesize FeNPs that are useful for removal for malachite green dye.

苹果皮提取物生物合成铁纳米颗粒用于孔雀石绿染料的脱色

这项研究探索了苹果皮提取物（APE）在铁纳米颗粒（FeNPs）的生物合成中的潜在用途。合成的APE-FeNPs通过紫外-可见光谱，傅里叶变换红外光谱（FTIR），场发射扫描电子显微镜（FE-SEM），能量色散X射线光谱（EDX）和透射扫描电子显微镜（ TEM）。通过将多酚峰（237 nm，272 nm）检测为生物组分整合到APE-FeNPS中，证实了APE-FeNPs的生物合成，并且FTIR分析分析了主要官能团（OH-，NH-，CH-弯曲振动）的存在。形成的APE-FeNP为椭圆形和球形，尺寸为50 nm。用APE-FeNPs处理孔雀石绿染料在前1分钟内显示71.51％的染料脱色。
