摘要
采用脉冲-红外吸收法测定氟化稀土中氧的质量分数.实验确定了测定氧量的最佳分析条件:采用石墨坩埚,以镍箔为助熔剂,在"6.0kW/25s"的最佳条件下进行定量分析.回收率达到103.45%～105.9%,相对标准偏差为3.98%～5.69%.
This paper studies the determination of mass fraction of oxygen in fluorinated rare earth by pulse infrared absorption method.experiments showed the following optimized conditions： graphite crucibles as vessel and nickel foil as flux in 6.0kW/25s.The recovery rate reached 103.45 % ～ 105.9 % and the relative standard deviation falls between 3.98 % and 5.69 %.
