【摘要】 在室温、N2保护和搅拌条件下,我们利用硼氢化钠作为还原剂成功的合成出Ni/Au纳米粒子,并通过改变摩尔比合成出不同配比的Ni/Au纳米粒子。利用Uv-vis吸收光谱、能谱(EDS)、扫描电子显微镜(SEM)分别对其进行了表征研究。将制备的Ni/Au纳米粒子应用于鲁米诺化学发光体系中,发现在碱性条件下Ni/Au纳米粒子对鲁米诺-高锰酸钾体系有明显的增强作用。通过实验我们进一步研究了鲁米诺-高锰酸钾体系的最佳实验条件,在优化后的最佳实验条件下,研究了几种氨基酸、药物以及有机物对该发光体系的影响。发现某些物质对其有很明显的作用,然后利用Uv-vis吸收光谱、荧光光谱、化学发光光谱研究了该体系可能的化学发光机理。更多还原

【Abstract】 In this paper,Ni/Au NPs was prepared via sodium borohydride as reductant under stirring and Nitrogen conditions at room temperature.And different ratios of Ni/Au NPs was prepared by changing the [AuCl4-] / [Ni2 +] molar ratio.The Uv-vis absorption spectrum,energy spectrum(EDS),scanning electron microscopy(SEM) were carried out for characterization of as-obtained Ni/Au NPs.We used the Ni/Au NPs in luminol chemiluminescence(CL) system,and found it had a significant enhancement of luminol-KMnO4 system in alkaline condition.Then we researched the optimization of luminol-KMnO4-Ni/Au NPs system experimental conditions.Under the optimization conditions,we studied several amino acids,drugs and organic compounds effect on the CL system,then we investigated the CL mechanism of the System through Uv-vis absorption spectra,Fluorescence spectroscopy and Chemiluminescence Spectra.更多还原
