路易斯碱对金的化学蒸气发生效率增强的初步研究

提出了某些带有孤对电子的路易斯碱能够增强过渡和贵金属化学蒸气发生（CVG）效率的观点,并使用无色散原子荧光研究乙醚、四氢呋喃和三乙胺对金的CVG效率增强效果进行了验证。研究表明,3种路易斯碱都能使金的荧光信号增强,其增强效果与DDTC相似。在最佳条件下,金的标准校正曲线相关性大于0.99,检出限（3σ）为1μg/L,精密度为5%。...

Summary:提出了某些带有孤对电子的路易斯碱能够增强过渡和贵金属化学蒸气发生（CVG）效率的观点,并使用无色散原子荧光研究乙醚、四氢呋喃和三乙胺对金的CVG效率增强效果进行了验证。研究表明,3种路易斯碱都能使金的荧光信号增强,其增强效果与DDTC相似。在最佳条件下,金的标准校正曲线相关性大于0.99,检出限（3σ）为1μg/L,精密度为5%。

Lewis bases with lone-pair electrons were found to enhance the efficiency of chemical vapor generation（CVG） of gold with NaBH4 as the reductant.Such effect was tested by using ether,tetrahydrofuran,and triethylamine as the Lewis bases and a nondispersive atomic fluorescence spectrometer as detector.The results showed that the Lewis bases and DDTC gave similar enhancement effect for the CVG of gold.The detection limit and precision were found to be 1 μg/L and 8%（RSD）,respectively.The results showed that Lewis bases with lone-pair electrons played an important role in the enhancement of the CVG efficiency of gold.
