摘要
提出以五氧化二钒和碳粉为混合助融剂高温热解地质样品,平台石墨炉T1I分子吸收光谱法测定地质样品中痕量碘。方法简便、可靠,标准物质测定结果与推荐值吻合。
A useful method is proposed for the determination of trace amounts of iodine in geological samples by molecular absorption spectrometry of thallium iodide with platform graphite furnace.Pyrolysis has been established as an effective method using mixture flux(vanadium pentaxide and carbon powder) to be used for release of iodine in geological samples.Test were carried out to optimize the pyrolysis temperature,sample/mixture flux ratio and collecting solution volume.Determination results of the standard samples with thier recommended value are agreement.
