Abstract

The plant-mediated nanoparticles synthesis process is gaining popularity because of its effective cost, eco-friendliness, and nontoxic nature. The current study presents the silver nanoparticles (AgNPs) which synthesized with AgNO3 as precursor salt and Jatropha curcas leaf extract. J. curcas leaf extract has phytochemicals that could reduce the precursor metal salt to nanoparticles and act as a capping agent surround the nanoparticles to enhance its stability. Phytochemical screening on J. curcas leaf extract showed that alkaloids, saponins, tannins, flavanoids, steroids, philobatannins, phenols, and cardiac glycosides are contained in the sample. The biosynthesized nanoparticles were investigated by UV-visible (UV-vis) spectroscopy, X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). UV-vis spectroscopy confirmed the fabrication of AgNPs at 250–400 nm. The solutions’ change of color from pale yellow to reddish brown indicated that AgNPs is formed. XRD analysis revealed that the synthesized AgNPs average crystal size was 36.4 nm. FTIR analysis indicated that the organic residues covered the nanoparticles. The inhibitory properties of the solution of the synthesized nanoparticles and the bulk extract were evaluated using medium carbon steel. The solution of the synthesized nanoparticles (10 ml) showed better corrosion inhibition efficiency of 87.10 % compared with the bulk

麻疯树叶提取物纳米银的生物合成及表征:缓蚀活性分析
植物介导的纳米颗粒合成工艺因其有效的成本、生态友好性和无毒性而越来越受欢迎。研究了以AgNO3为前体盐和麻疯树叶提取物合成纳米银的方法。麻叶提取物中含有的植物化学物质可以将前体金属盐还原为纳米颗粒,并在纳米颗粒周围起到封盖剂的作用,提高其稳定性。对麻瓜叶提取物进行植物化学筛选,结果表明麻瓜叶提取物中含有生物碱、皂苷、单宁、黄酮类化合物、甾体、绿巴丹宁、酚类化合物和心苷类化合物。采用紫外可见光谱(UV-vis)、x射线衍射(XRD)和傅里叶变换红外光谱(FTIR)对生物合成的纳米颗粒进行了研究。紫外可见光谱证实了AgNPs在250 ~ 400 nm处的制备。溶液颜色由淡黄色变为红棕色,表明AgNPs形成。XRD分析表明,合成的AgNPs平均晶粒尺寸为36.4 nm。红外光谱分析表明,有机残留物覆盖了纳米颗粒。采用中碳钢对合成的纳米颗粒和散装提取物溶液的抑菌性能进行了评价。合成的纳米颗粒溶液(10 ml)的缓蚀效率为87.10%
