微量硅的测定方法,目前国内多采用硅钼兰比色法,本法虽灵敏,但操作繁琐。近年来文献报道有原子吸收分光光度法,X荧光光谱法,火焰光度法和中子活化法等,在这些方法中,有的很难获得准确结果,有的操作虽简便、准确、但仪器设备昂贵、目前尚难普遍应用。脉冲极谱法测定痕 Determination of trace silicon, the current use of silicon molybdenum blue colorimetric method, although this method is sensitive, but the operation cumbersome. In recent years, there are reports in the literature of atomic absorption spectrometry, X-ray fluorescence spectrometry, flame photometry and neutron activation method, in these methods, some are difficult to obtain accurate results, although some operations are simple and accurate, but the equipment Expensive, it is difficult to universally applied.
