无水浴砷铈催化光度法测定微量碘

对砷铈催化光度法这一微量碘的最常用测定方法进行了改进，取消了原方法中所有的水浴步骤，选用了更合适的反应器皿和反应终止剂，对试剂纯化进行了讨论，碘含量为０～１０００μｇ／Ｌ的范围内，校正曲线的线性相关系数大于０．９９９。

国际地球化学标准参考样品分析

The analytical procedures used for many years in our institute for rock analysis are tested against 18 international geochemical reference samples provided by CRPG, ANRT and USGS. The validity of our method and its suitability for widely different samples are substantiated by the good agreement between our results and the recommended values.
