本文通过对超声平衡雾化-集中进样火焰原子吸收法特点的研究,提出了一种简便、快速的“注入”式分析测试技术。该技术可在雾化腔内用同一试液通过“注入”方式完成标准曲线或标准加入法,从而增加了分析效率。方法的准确性和重复性都是满意的。
In this paper, a simple and rapid “injection” analysis and testing technique is proposed based on the study of the characteristics of the ultrasonic balanced atomization-concentrated sampling flame atomic absorption spectrometry. The technology can be used in the spray chamber with the same test solution by “injection” to complete the standard curve or standard addition method, thereby increasing the efficiency of the analysis. The accuracy and repeatability of the method are satisfactory.
