钛中杂质元素的直接光谱测定是由于金属标样的不易制作而难以实现,但可令其转化成二氧化钛后用粉末光谱法进行测定。然而测定其中廿余种杂质元素的光谱方法所见不多,同时测定难、易挥发元素更显困难。这主要是钛基体元素谱线以及某些被测元素谱线之间的相互干扰和影响;同时,二氧化 The direct spectroscopic determination of the impurity elements in titanium is difficult to achieve due to the difficulty of making the metal standard, but it can be measured by powder spectroscopy after it is converted to titanium dioxide. However, the determination of more than twenty kinds of impurity elements in the spectrum method not seen much, while the determination of difficult, volatile elements more difficult. This is mainly due to the mutual interference and influence between the titanium matrix elemental lines and some of the detected elemental lines; meanwhile,
