摘要
采用热中子活化分析和超热中子活化分析,测定了铬铁矿石和铜镍矿石中的铱。实验表明,采取超热中子活化和长冷却时间的分析方案,铱的分析检出限可达0.94×10^(-9)g。
Thermal neutron activation analysis and epthermal neutron analysis are adoped to determine Ir in chromites and copper nickel sulphide ores. It is shown that Ir detection limit can arrive at 0.94×10^(-9) g with epthermal neutron activation and counting after a long cooling time.
