燃烧－离子色谱法测定地质物料中的硫

Determination of Sul fur in Geological Material s by Combustion-Ion Chromatography

文章介绍了用自制氧瓶，氧气燃烧－离了色谱法测定地质物料中Ｓ。实验了最佳吸收条件。对含Ｓ为０．０８６％的地球化学标样ＧＳＲ－４测定６次，其平均值为０．０８４％，相对标准偏差ＲＳＤ为１．５８％。

he material was decomposed by closed-flask combustion in oxygen atmosphere.Experiments were made for the optimization of the absorption conditions. The method has beenapplied to the analysis of the geochemical CRM GSR-4(S,0.086%),and RSD of 1.58%wasObtained(n=6).
