本文研究了共显色效应对稀土元素光度分析的影响;探讨了在TRS-80型微处理机上用回归分析法处理实验数据问题。结果表明,在镧存在下用偶氮氯膦Ⅲ测定钇,可使测量误差从+26±15％降低至+3.6±3.0％。该方法简单、快速。
In this paper, the effect of co-chromogenic effect on the photometric analysis of rare earth elements is studied. The problem of experimental data processing by regression analysis on TRS-80 microprocessor is discussed. The results show that measurement of yttrium with chlorophosphonazo III in the presence of lanthanum reduces the measurement error from + 26 ± 15% to + 3.6 ± 3.0%. The method is simple and fast.
