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