本文对残液中锑的测定——原子吸收光谱法最佳仪器工作条件,杂质干扰、酸度的影响进行了试验。结果表明:在波长217.6nm,7～10%盐酸介质,氧化性兰色火焰条件下,测定的灵敏度较高,吸光度稳定,共存离子不干扰测定,回收率为95%～103%,变异系数为1.83%～2.43%,方法简便快速,结果满意。 In this paper, the determination of antimony in raffinate - the best instrument operating conditions of atomic absorption spectrometry, impurity interference, acidity effects were tested. The results showed that under the condition of 217.6nm wavelength, 7 ~ 10% hydrochloric acid medium and oxidative blue flame, the sensitivity and the absorbance were stable. The coexisting ions did not interfere with the determination. The recoveries ranged from 95% to 103% and the coefficients of variation were 1.83% ~ 2.43%, the method is simple and quick with satisfactory results.
