铼酸钾为制取金属铼的重要原料,铼酸钾中杂质含量则直接影响高熔点金属铼的纯度。对铼酸钾中杂质分析国内外报导甚少,一般还需要和基体分离方能测定。我们应用美国 Perkin—Elmer 公司的703型原子吸收分光光度计-400型石墨炉-AS-40型自动取样器,采用石墨 Potassium rhenium is an important raw material for the preparation of metallic rhenium. The impurity content of potassium rhenium directly affects the purity of rhenium with high melting point. On the rhenium impurity analysis at home and abroad little, generally also need to be separated from the matrix before being measured. We use the United States Perkin-Elmer’s 703 atomic absorption spectrophotometer -400 graphite furnace -AS-40-type autosampler, the use of graphite
