摘要
采用氧化镁-硝酸钠-过氧化氢处理试样,不需分离富集,电感耦合等离子体发射光谱法直接测定钼矿石及铜矿石中的铼,筛选了不同溶矿方法和仪器参数条件。方法检出限为0.014μg/g,相对标准偏差(RSD,n=11)小于5.00%,经国家一级钼矿石及铜矿石标准物质分析验证,结果与标准值吻合。
The determinations of rhenium in molybdenum and copper ores were performed by inductively coupled plasma-atomic emission spectrometry （ICP-AES） with sample pretreatment using magnesium oxide-sodium nitrate-hydrogen peroxide. The sample pretreatment parameters and instrument operating conditions were optimized. The detection limit of the method for Re was 0. 014μg/g. The method has been verified by determination of Re in molybdenum ore and copper ore National Standard References and the results are in agreement with certified values with precision of less than 5.00% RSD （ n = 11 ）.
