天青石、硅酸盐及其它矿物试样中锶的测定多采用碱熔分解,这不但手续繁长,且引入大量盐类,不利于用原子吸收或ICP法测定。我们在绵拔邦彦工作的基础上,试验了用氢碘酸-氢氟酸分解试样,并拟定了分解条件。以人工合成试样进行实验,结果回收率达99.5—101.2%,表明分解试样完全,效果好。并且与碱熔法的测定结果作了对照,测定值基本吻合。利 Determination of strontium in celestite, silicate and other mineral samples to use more alkaline melting decomposition, which not only the long process, and the introduction of a large number of salts, is not conducive to the use of atomic absorption or ICP determination. On the basis of our work, we tried to decompose the sample with hydroiodic acid-hydrofluoric acid and set up the decomposition conditions. Artificial synthetic samples for the experiment, the results of the recovery rate of 99.5-101.2%, indicating that the decomposition of the sample is complete, the effect is good. And compared with the results of alkali melting method, the measured values ​​are in good agreement. Lee
