摘要
本工作较系统地研究了在交流电弧中不同量的共存稀土元素镝,钛,铒,铥和镱对某些被测稀土元素光谱线强度的影响.用交流电弧激发溶液于渣样品,其样品是在固定量的被测元素溶液中各自分别加入不同量的共存元素镝、钛、铒、铥和镱,摄谱后测量各被测元素的光谱线强度对共存元素在溶液中各个不同浓度作关系曲线.从关系曲线上看出各不同共存元素对不同的被测元素影响是不同的,其存在量的不同影响也不一样.
The effect of coexistent rare earth elements (Dy, Ho, Er, Tm and Yb) on the spectral line intensities of certain detected rare earth elements (La, Ce, Pr, Eu, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y) in alternating current (AC) arc was studied systematically. The samples emitted by AC arc different and the quantity of coexistent elements (Dy, Ho, Er, Tm and Yb) was added in the sample detected. The spectral line intensities of detected elements were measured. The correlative curves of the concentrations of coexistent rare earth elements and the spectral line intensities of detected rare earth elements were obtained. It has been found that the effect is different at different compositions or concentrations of the coexistent rare earth elements(Dy, Ho, Er, Tm and Yb).
