The enhancement effect of double complexing agents on ytterbium is studied.Citrate, tartrate,EDTA, urea, and 5-sulfosalicylic acid are chosen as complexing agents. When the sum of the molar concentration of two complexing agents is kept constant as their ratio is varied, three types of enhancement effect, namely competitive, additive and synergistic, are found. The mechanism of the enhancement, the distribution of ytterbium atoms in the flame and the interferences of the concomitant elements and their elimination...

The enhancement effect of double complexing agents on ytterbium is studied.Citrate, tartrate,EDTA, urea, and 5-sulfosalicylic acid are chosen as complexing agents. When the sum of the molar concentration of two complexing agents is kept constant as their ratio is varied, three types of enhancement effect, namely competitive, additive and synergistic, are found. The mechanism of the enhancement, the distribution of ytterbium atoms in the flame and the interferences of the concomitant elements and their elimination are studied. The sensitivity is increased to 0.15ppm/1% absorption. The results show that double complexing agents are more sensitive and selective for the determination of ytterbium than single complexing agents.

The enhancement effect on ytterbium absorption is studied by organic complexing agents containing donor atom oxygen or/and nitrogen in an air-acetylene flame. The results indicate that the complexing agent systems are more sensitive and more selective for the determination of ytterbium than the system without the complexing agent. The method has been applied to determination of ytterbium in synthetic sample with satisfactory results.

本文在空气-乙炔焰中,借加入有机络合剂以提高能形成难离解氧化物的稀土的灵敏度。以镱为例,研究了含键合原子氧或氧、氮的络合剂对镱的增感效应和镱原子在火焰中的分布。Yb灵敏度达0.17μg/ml/1%吸收,选择性显著提高。本法用于合成样品中镱的测定,结果满意。

This paper focuses on the study of the influences of neodymium,yttrium,lanthanum,europium and samarium on the determination of ytterbium by air-acetylence flame atomic emission spectrometry in the medium of hydrochloric acid,nitric acid and perchloric acid.Ytterbium was determined in the medium of 1% perchloric acid using 1000μg/ml lanthanum as the sensitive agent.This method has high selectivity.A large amount of common non-ytterbium rare-earth and non-rare-earth elements do not interfere.The linear range of the calibration curve of ytterbium is 0-20μg/ml Yb,detection limit is 0.14μg/ml.This method has been used in the determination of trace amounts of ytterbium in the mixture of rare-earth oxides.as well as crude products of yttria with satisfactory results.
