摘要
硝酸于聚四氟乙烯闷罐中消解样品 ,石墨炉原子吸收光谱法测定催化有机残液中的微量铑 ,相对标准偏差为 6 .2 %,回收率为 96 .5 %— 1 0 5 .4 %。方法简便、快速 ,分析结果令人满意。
Trace noble metal Rh in catalytic organic residue was digested with HNO_3 at 130℃ for 12h,and determined by graphite furnace atomic absorption spectrometry.The recovery rates of the method are 96.5%—105.4% with the relative standard deviation of 6.2%.The method was applied to the analysis of some practical sample with satisfactory results.
