Abstract

Agricultural and environmental samples are digested with acid, and arsenic and selenium are determined using hydride generation atomic absorption spectrometry. Interelement interferences are eliminated by high acid concentrations or cation-exchange resins. Agreement with standard reference material is excellent. The technique is also applied to actual samples.

摘要

农业和环境样品用酸进行消解，然后使用氢化物发生原子吸收光谱法测定砷和硒。通过高酸浓度或阳离子交换树脂消除元素间干扰。与标准参考物质的一致性非常好。该技术也应用于实际样品。
